3x−4y=−24 Response : A. y=34x+6 B. y=−6x−34 C. y=6x−34 D. y=−34x+6
Answers
Answer:
y = 3/4 x +6
Step-by-step explanation:
3x−4y=−24
Solve for y
Subtract 3x from each side
3x-3x−4y=-3x−24
-4y = -3x-24
Divide each side by -4
-4y/-4 = -3x/-4 -24/-4
y = 3/4 x +6

Instructions
Sarah’s neighbor offers to pay her $5 for every shark tooth she finds on the beach. After collecting only three shark’s teeth, Sarah decides to share the opportunity with her friend John. Sarah can find shark teeth twice as fast as John, but she can earn even more money with his help.
Sarah can use the expression 5(2j + 3 + j) to represent the amount of money she can earn.
Part 1: Writing Expressions
1. Write an expression that looks like Sarah’s expression: 5(2j + 3 + j). Replace the coefficients so that your expression is not equivalent. You may use any number that you choose to replace the coefficients. Be sure to leave the variables the same. For example, 8(3j + 7 + 3j) looks like Sarah’s expression but is not equivalent.
2. Translate the algebraic expression you created in Question 1 to a verbal expression.
Part 2: Writing Equivalent Expressions
3. You will now use mathematical properties to create two expressions that are equivalent to the expression you created in Question 1. Make sure you show all steps in your work.
a. Use either the commutative property or combine like terms to create an equivalent expression.
b. Use the distributive property to create an equivalent expression.
4. Pick a number from 1 to 10. Use that number to verify your three expressions (the original, the one from 3a, and the one from 3b) are equivalent by substituting it into each expression. Show all your work for complete credit.
Part 3: Finish the Story
5. Write a few sentences to end Sarah’s story. How many shark teeth did she find? How many shark teeth did John find? How much money did Sarah earn?
6. Choose a method to present your assignment. You may submit your work in a Word Document or you may choose to develop a PowerPoint presentation or video recording of yourself. Use your creativity! Make sure to include the information from all three parts in your Word Document or presentation.

Answer:
Sarah’s neighbor offers to pay her $5 for every shark tooth she finds on the beach. After collecting only three shark’s teeth, Sarah decides to share the opportunity with her friend John. Sarah can find shark teeth twice as fast as John, but she can earn even more money with his help.
Sarah can use the expression 5(2j + 3 + j) to represent the amount of money they can earn.
Part 1: Writing Expressions
Q1. Write an expression that looks like Sarah’s expression: 5(2j + 3 + j). Replace the coefficients so that your expression is not equivalent. You may use any number that you choose to replace the coefficients. Be sure to leave the variables the same. For example, 8(3j + 7 + 3j) looks like Sarah’s expression but is not equivalent.
25(10j + 18 + 5j)
Your expression is good.
Q2. Translate the new algebraic expression you created in Question 1 to a verbal expression.
Skuttle offered to pay his sister Izzy $25 for every four leaf clover she finds in the woods. Izzy finds 18 clovers but decides to get Roxy’s help. Izzy finds clovers twice as fast as Roxy but they will over all make more money together.
Your verbal expression is good. It refrects your chosen equation.
Part 2: Writing Equivalent Expressions
Q3. Use your knowledge of the mathematical properties to create two equivalent algebraic expressions for the algebraic expression you created in Question 1. Explain how you arrived at the equivalent expressions by showing all your steps and stating which properties you used.
Using commutative property of addition, the expression in question 1 can be rewritten as follows:
25(10j + 18 + 5j) = 25(10j + 5j + 18)
Using distributive property of multiplication over addition, the expression in question 1 can also be rewritten as follows:
25(10j + 18 + 5j) = 250j + 450 + 125j
Q 4. Use substitution to prove your algebraic expressions are equivalent. You may substitute any number for the variables you choose. Show all your work for complete credit.
Now we can subsitute, say 7 for j.
For the first expression, we have:
25(10j + 5j + 18) = 25(10(7) + 5(7) + 18)
= 25(70 + 35 + 18) = 25(123) = 3,075.
For the second expression, we have:
250j + 450 + 125j = 250(7) + 450 + 125(7) = 1,750 + 450 + 875 = 3,075.
Thus, we can see that both expressions are equivalent.
Part 3: Finish the Story
Q5. Write a few sentences to end Sarah’s story. How many shark teeth did she find? How many shark teeth did John find? How much money did they earn?
Sarah found 3 + 7 = 10 shark teeth.
John found 10 / 2 = 5 shark teeth.
The total money they earned is $5 x 15 = $75.

56.7+23.44 useing front-end to estimate the sum
Answers
Answer:
Step-by-step explanation:
To estimate the sum of 56.7 and 23.44 using the front-end method, you can round each number to the nearest whole number and then add them together. This will give you an estimate of the sum that is close to the actual result.
Using this method, you would round 56.7 to 57 and 23.44 to 23, and then add them together to get an estimate of 80. This is a reasonable estimate of the sum of 56.7 and 23.44, which is actually 80.14.
Note that this method is not as accurate as using a calculator or performing the exact calculation, but it can be a useful tool for quickly estimating the sum of two numbers.
Answer:80
Step-by-step explanation: 56.7 when rounded is 57 and 23.44 rounded is 23 so 57+23 is 80

Answers
Answer:
(A) The scatter plot is attached below.
(B) The outlier is at (189, 16°F).
(C) There is a negative correlation.
(D) The dependent variable is sales and independent variable is the temperature.
Step-by-step explanation:
The data provided for Hot chocolate sales and outside temperatures is as follows:
Sales (Y) Temperature (X)
100 92
213 88
830 54
679 62
209 85
189 16
1110 52
456 65
422 68
235 89
199 91
(A)
The scatter plot is attached below.
(B)
A cluster is a collection of points or values at one place.
On the scatter plot there is a cluster of three values between the temperatures 80°F to 100°F.
An outlier is a value that is very different from the other values in a data set. It is either too small or too large.
There is an outlier present in the provided data set.
The outlier is at (189, 16°F).
(C)
The point on the scatter plot are downwards sloping.
This implies that there is a negative relationship between the variables temperature and sales.
Thus, there is a negative correlation.
(D)
Dependent variables are those variables that are under study, i.e. they are being observed for any changes when the other variables in the model are changed.
Independent variables are the variables that are being altered to see a proportionate change in the dependent variable.
In this case the data represents the sales of hot chocolate according to the temperature outside.
So, the dependent variable is sales and independent variable is the temperature.
This is because as the temperature decreases the sales of hot chocolate increases.

A triangular prism is attached to a rectangular prism as shown below.
If w = 8 inches, x = 5 inches, y = 20 inches, and z = 11.3 inches, what is the total surface area of the EXTERIOR FACES of the figure?
(Answer choices in picture!!) (I WILL GIVE BRAINLIEST)
Answers
Surface area of the triangular prism:
The triangular prism has two triangular faces and three rectangular faces.
The triangular faces have base (x) of 5 inches and height (y) of 20 inches. The surface area of each triangular face is (1/2) * base * height = (1/2) * 5 * 20 = 50 square inches.
The rectangular faces have dimensions (w, y, and z) of 8 inches, 20 inches, and 11.3 inches, respectively. The surface area of each rectangular face is length * width. Adding the surface areas of the three rectangular faces, we get: 2 * (w * y) + 2 * (w * z) + 2 * (y * z) = 2 * (8 * 20) + 2 * (8 * 11.3) + 2 * (20 * 11.3) = 320 + 180.8 + 452 = 952.8 square inches.
Surface area of the rectangular prism:
The rectangular prism has six rectangular faces.
The dimensions of the rectangular prism are (w, x, and y) of 8 inches, 5 inches, and 20 inches, respectively. The surface area of each rectangular face is length * width. Adding the surface areas of the six rectangular faces, we get: 2 * (w * x) + 2 * (w * y) + 2 * (x * y) = 2 * (8 * 5) + 2 * (8 * 20) + 2 * (5 * 20) = 80 + 320 + 200 = 600 square inches.
Total surface area of the exterior faces:
To find the total surface area of the exterior faces, we add the surface areas of the triangular prism and the rectangular prism: 50 + 952.8 + 600 = 1,602.8 square inches.
Therefore, the total surface area of the exterior faces of the figure is approximately 1,602.8 square inches. However, none of the given answer choices match this value. Please recheck the given dimensions or options provided.

How to simplify the expression?The expression in the context of this problem is defined as follows:
(-3.78b + 12) - (4.82b - 16).
The negative sign before the parenthesis means that the sign of each term inside the parenthesis is changed, hence:
-3.78b + 12 - 4.82b + 16.
This is the step where Maddie made the first error.

Sula designs greeting cards for her friends. Each friend has a 30% chance to get a musical greeting card. Design a simulation that can be used to estimate the probability that a friend will receive a musical greeting card.
Answers
Here's a simple Python code that simulates the process:
```python
import random
num_friends = 1000 # the number of friends
num_musical_cards = 0 # the number of friends who received musical cards
# simulate the card distribution for each friend
for friend in range(num_friends):
if random.random() < 0.3:
num_musical_cards += 1
# calculate the probability of a friend receiving a musical card
prob = num_musical_cards / num_friends
print("Probability of a friend receiving a musical card:", prob)
```
In this simulation, we create a loop that simulates the card distribution for each friend. We randomly assign a musical card to each friend with a 30% chance. Then, we calculate the probability of a friend receiving a musical card by dividing the number of friends who received musical cards by the total number of friends.
You can adjust the `num_friends` and `random.random() < 0.3` parameters to match your specific scenario.

Answers
Answer:
Step-by-step explanation
For the first sum you nee to find the same coefficient or add or subtract a number
\(-x^3 -2x -7\)
This the simplified version of the sum above. I have basically subtracted -2x^3 by x^3 to make -x^3. Then I have subtracted -3x and x to make -2x. Finally I have added -4 and -3 as the rule suggests to add two numerals the minus symbol on both of them.
The next sum we have to simplify both numerals so we know if both sum’s answer are
\(-x^3 -2x -7-x^3 -2x -7\)
After simplifying them, both of them have the same answer, so the statement is true. To explain this, we could say that the sums were basically rotated around to trick us but the answer is still the same
