I need also help on -2(x+3)=_-6
Answers
The solution to the equation -2(x + 3) = -6 is x = 0.
To simplify the expression 5t + 7 + 8b, we can combine like terms.
There are two like terms in the expression: 5t and 8b.
Combining the like terms gives us:
5t + 8b + 7
Therefore, the simplified form of the expression 5t + 7 + 8b is 5t + 8b + 7.
Regarding the equation -2(x + 3) = -6:
To solve this equation, we can follow these steps:
Distribute the -2 to the terms inside the parentheses:
-2 * x + (-2) * 3 = -6
This simplifies to:
-2x - 6 = -6
Move the constant term to the right side by adding 6 to both sides of the equation:
-2x = 0
Divide both sides of the equation by -2 to isolate the variable x:
x = 0 / -2
Simplifying the right side of the equation gives us:
x = 0
The solution to the equation -2(x + 3) = -6 is x = 0.
The simplified expression 5t + 7 + 8b remains as 5t + 8b + 7, and the solution to the equation -2(x + 3) = -6 is x = 0.

The value of line RS is 23
How to determine the valueFrom the diagram shown, we have that line PS, line PQ, line QR and line RS form a square.
Note that the sides of a square are equal to each other.
The relationship is represented as;
Line PS = Line PQ = Line QR = Line RS
We have that;
Line PS = 6x - 5Line RS = 9x - 4Substitute the expressions
6x - 5 = 9x - 4
Now, collect like terms
6x - 9x = - 4 - 5
Subtract the like terms
-3x = -9
Make 'x' the subject of formula
-3x/-3 = -9/-3
x = 3
Then, RS = 9x - 4 = 9(3) - 4 = 27 - 2 = 23
Hence, the value is 23

Answers
A) For the y-intercept. The cost of the rental fee at 0hour is $100.
B) The rate of the price of the hall with respect to the time is 66.7 dollars/hour
The y-intercept of the graph is the point where the line cuts the y axis. From the graph, we can see that the line cuts the y-axis at y = 100
This means that the cost of rental fee at 0 hour is $100.
To get the slope of the graph, we will use the coordinate point (0,100) and (3,300)
\(Slope =\frac{300-100}{3-0}\\Slope = \frac{200}{3}\\Slope = 66.7\)

Answers
we calculated confidence interval = 0.48±0.16
what is confidence interval?confidence interval represents the accuracy of a particular estimation.
what is proportion of sample?
proportion of population is the ratio of random sample to the total available sample.
Given, size of samples that means number of total iPhones, n = 25
size of random samples that means iPhone with 85 downloaded apps, p= 12,
critical value for 90% confidence interval z* = 1.65
proportion of samples, p^ = p/n = 12/25 =0.48
finally, confidence interval = p^±z*[√{p^(1-P^)/n}]
0.48±1.65[√{0.48(1-0.48)/25}]
hence, the confidence interval = 0.48±0.16

Solve for r 1+3r>10 please I need this solved aspap
Answers
The solution to the inequality 1 + 3r > 10 is r > 3.
This means that any value of r greater than 3 will satisfy the inequality.
To solve the inequality 1 + 3r > 10, we need to isolate the variable r on one side of the inequality sign.
Let's begin by subtracting 1 from both sides of the inequality:
1 + 3r - 1 > 10 - 1
This simplifies to:
3r > 9
Next, we can divide both sides of the inequality by 3 to solve for r:

Three friends shares an amount in a ratio of 2/3,3/5 and 1/4 .if the largest share was Le 12,000.00.How much was shared between them
Answers
The total amount shared by three friends = 27300$
Three friends' shares are 12000$, 10800$, 4500$.
Largest share received = 12000$
The ratio of three friends = 1st: 2nd: 3rd
= 2/3: 3/5: 1/4
We will take the LCM of the denominators and then convert these, unlike fractions into like fractions.
= 2/3: 3/5: 1/4
60 is the LCM of 3, 5, and 4.
⇒ 40 / 60 : 36 / 60 : 15 / 60
⇒ The ratio is 40: 36: 15
Sum of the ratio = 40 + 36 + 15 =91
Let the total amount be x
However, given that the largest share received = 12000$
We can use this to calculate the total amount.
By this to find the total amount we get
= 40 x = 12000 * 91
= x = 12000 * 91 / 40
= x = 300 * 91
= x = 27300
Share of 2nd friend = 36 * 27300 / 91
= 36 * 300
= 10800 $
Share of 3rd friend = 15 * 27300 / 91
= 15 * 300
= 4500 $
Therefore, the total amount shared by three friends = 27300$
The shares of three friends are 12000$, 10800$, 4500$.

The mean of a normally distributed data set is 45, and its standard deviation is 7. For this data, the probability of which range of numbers is represented by the area of the shaded region in the given curve?
31 to 45
38 to 52
45 to 59
24 to 38
Done
Answers
The probability of the range of numbers represented by the shaded region in the given curve is best described by option B: 38 to 52.
To determine the range of numbers represented by the shaded region in the given curve, we need to find the probability associated with that region. In a normal distribution, the area under the curve represents the probability.
Since the mean of the data set is 45 and the standard deviation is 7, we can use the properties of the normal distribution to determine the range of numbers represented by the shaded region.
Let's analyze the answer choices:
A. 31 to 45: This range is to the left of the mean. It does not include the shaded region.
B. 38 to 52: This range is within one standard deviation of the mean. It is likely to include the shaded region.
C. 45 to 59: This range is to the right of the mean. It does not include the shaded region.
D. 24 to 38: This range is more than one standard deviation below the mean. It does not include the shaded region.
Based on the given information, option B, 38 to 52, is the most likely range of numbers represented by the shaded region. This range falls within one standard deviation of the mean, which is a common measure of probability in a normal distribution.
Therefore, the probability of the range of numbers represented by the shaded region in the given curve is best described by option B: 38 to 52.

What is polynomials?
Using variables and coefficients, polynomials are algebraic expressions. The term "indeterminates" is sometimes used to describe variables. The terms Poly and Nominal, which together signify "many" and "terms," make up the word polynomial. When exponents, constants, and variables are combined using mathematical operations like addition, subtraction, multiplication, and division, the result is a polynomial (No division operation by a variable). The expression is categorized as a monomial, binomial, or trinomial based on the number of terms it contains.

Answer:

Step-by-step explanation:
Note how both triangles are isosceles triangles, which mean two angles will be equivalent. In the triangle with the marked angle measurement, since the total of angles in a triangle is 180, then the measurement of the unmarked angles have a sum of 180-64, which is 116. Then, as stated before, this triangle is isosceles, so the measurement of each unmarked angle is 116/2, which is 58.
Next, notice how the angle below angle x in that triangle shares a line with one of the 58 degree angles. This means that angle is 180-58, which is 122. Now, since the total of angles in a triangle is 180 and the triangle is isosceles, then angle x is (180-122)/2, which is 58/2, or 29 degrees

A watermelon seed is 0.4cm long. How far would a line of 126 stretch?
Answers
Answer:
0.504m
Step-by-step explanation:
First, we would multiply 0.4cm by 126 watermelon seeds to find the length of the line in cm.
0.4*126
= 50.4cm
Therefore, the line of watermelon seeds stretches 50.4cm.
Now, because the question wants us to type the answer in meters, we must convert 50.4cm into meters. We do this by dividing 50.4 by 100 since 100cm makes up 1 meter.
50.4/100
= 0.504m
Therefore, the line of watermelon seeds stretches 0.504m.
