-3x + 7 = -8
Answers
Answer:
x=5
Step-by-step explanation:
-3x+7=-8
Bring 7 to the other side, it becomes negative
-3x=-8-7
Signs are same on rhs so u add
-3x = -8+-7= -15
Bring -3 to the other side n divide
therefore,
x=-15/-3
= +5 (two negatives become positive)
Hope it helps!
Answer:
x = 5
Step-by-step explanation:
→Subtract 7 from both sides:
-3x + 7 = -8
-3x = -15
→Divide both sides by -3:
x = 5

Find the original price.
Original Price:?
Discount: 20%
Sale price: $75
Answers
Answer:
$93.75
Step-by-step explanation:
The formula for finding original prices is o = s over 1 - d, in which o is the original price, s is the sale price, and d is the discount. Let’s go ahead and plug our numbers in: o = 75 over 1 - 0.2. (Remember 20% equals 20 ÷ 100.)
75 over 1 - 0.2 equals 75 over 0.8. Now we find out how much that is in whole numbers. 75 ÷ 0.8 = 93.75, o.

\( \boxed{ \bold{ \huge{ \boxed{ \sf{ - \frac{10}{27}}}}}} \)
Step-by-step explanation:
\( \sf{ - 3 \frac{1}{3} \div 9}\)
Convert the mixed number into improper fraction
\( \longrightarrow{ \sf{ - \frac{ 3 \times 3 + 1}{3} \div 9}}\)
\( \longrightarrow{ \sf{ - \frac{ 9 + 1}{3} \div 9}}\)
\( \longrightarrow{ \sf{ - \frac{ 10}{3} \div 9}}\)
Multiply the dividend by the reciprocal of the divisor. Reciprocal of any number or fraction can be obtained by interchanging the position of numerator and denominator
\( \longrightarrow{ \sf{ - \frac{ 10}{3} \times \frac{1}{9}}} \)
To multiply one fraction by another, multiply the numerators for the numerator and multiply the denominators for its denominator

\( \longrightarrow{ \sf{ - \frac{10}{27}}} \)

First we start with the formula for cylinders v=(pi)r(squared)h filled in Thats v=(3.14)(8 squared) (8) which brings us to the answer 1607.68 but you must round to the nearest tenth aka 1607.7
Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.
what is the answer for this problem? -8 - (-3)

12v = 48 + 4v
helpp p
Answers
Answer:
Therefore, the solution to the equation 12v = 48 + 4v is v = 6.
Step-by-step explanation:
To solve for v in the equation 12v = 48 + 4v, you can start by simplifying the equation by moving all the v terms to one side and all the constant terms to the other side:
12v - 4v = 48
Simplifying the left side of the equation gives:
8v = 48
To solve for v, you can divide both sides of the equation by 8:
v = 6
Therefore, the solution to the equation 12v = 48 + 4v is v = 6.
Answer:
Step-by-step explanation:
12v = 48 + 4v
Your first step is to subtract v from both sides:
8v = 48
Then, you divide each sides by 8 which gives you:
v = 6
That's your answer!

An isosceles triangle in which the two equal sides, labeled a, are longer than the base, labeled b. This isosceles triangle has two sides of equal length, a, that are longer than the length of the base, b. The perimeter of the triangle is 15.7 centimeters. The equation 2a + b = 15.7 models this information. If one of the longer sides is 6.3 centimeters, which equation can be used to find the length of the base? 6.3+b=15.7 12.6+b=15.7 2a+6.3=15.7 2a+12.6=15.7
Answers
Hey There!!
The answer to this is: isosollese triangle has 2 equal sides that are longer than legnth of base
perimiter=15.7
equation is 2a+b=15.7
so if the longer side is 6.3, wat is legnth of base
we know that identical sides are bigger so 6.3 is one of the identical sides
2a means the 2 idneical sides
2(6.3)+b=15.7
12.6+b=15.7
subtract 12.6 from btohs ides
b=3.1
Thus, answer is base=3.1 cm

Suppose instead that one friend bought all 4 bags of pretzels and another friend bought all 4 drinks write an expression that shows the total cost
Answers
Answer:
4x+4y=total cost
Step-by-step explanation:
We are given that there was a total of 4 bags of pretzels and 4 drinks bought. We are also given to write an expression using x dollars for the pretzels and y dollars for the drinks.
To do this, we need to multiply the cost of each pretzel bag, x, by the total amount of bags of pretzels purchased.
4·x
=4x
Next, we need to multiply the cost of each drink, y, by the total number of drinks purchased:
4·y
=4y
The question is asking us to write an expression, so put 2 and 2 together:
4x+4y=total cost
Given the actual question, "Suppose instead..." the expression would be the same.

A 5-pound bag of apples cost $3.50. Use that rate, to complete the table to identify equivalent ratios, and then answer the questions.
Apples ? 5 *? 15
Cost 0.70 3.50 7 ?
Answers
Answer:
Set up a proportion. 3.50 over 5 = x over 1 (x is what we are trying to find= the cost of 1 lb of apples)
Use cross products and multiply 3.50 by 1 to get 3.50 and then divide that by 5 to get 0.7.
So the apple cost 0.7 or seventy cents per pound.
