Answer: -1
Step-by-step explanation:
3( x +7 ) =18
8Use distributive property
3x + 21 = 18
Substract 21 from both sides
3x = -3
Divide 3 by both sides
x = -1
Another way to solve:
3( x +7 ) =18
Divide 3 by both sides
x + 7 = 6
Substract 7 by both sides
x = -1
Answer:
x = -1
Step-by-step explanation:
In order to answer this question, all we have to do is simplify the equation:
3(x + 7) = 18
3x + 21 = 18
-21 -21
3x = -3
/3 /3
x = -1
You can even put this answer in the equation to check.

Angela wants to purchase carpeting for her living room. The dimensions of her living room are 15 feet by 18 feet. If carpeting is sold by the square yard, determine how many square yards of carpeting she must purchase.
Answer: 15 square yards of carpeting.
Hope this helps!
Pretty sure i'm wrong on this one but I can't figure it out either.
Sorry if I wasted your time.
Angela must purchase 29.7 square yards of carpeting.
How to Convert Square Feet to Square yards?Multiply the area by the conversion ratio to convert a square foot measurement to a square yard measurement. Because one square foot equals 0.11 square yards, you may use the following easy formula to convert:
square inches = square feet × 0.11
The area in square inches is equal to the square feet multiplied by 0.11.
The dimensions of her living room are 15 feet by 18 feet.
The area in square feet is :
15 × 18 = 270 sq ft
Now, the area in square yards is :
270 × 0.11 = 29.7 sq yds
Thus, she must purchase 29.7 square yards of carpeting.

3/8 = r + 2/3 I really need help I don't get it!!
Answer:
-7/24 = r
Step-by-step explanation:
3/8 = r + 2/3
Subtract 2/3 from each side
3/8-2/3 = r + 2/3-2/3
3/8 - 2/3 = r
Get a common denominator or 24
3/8 *3/3 - 2/3 *8/8 =r
9/24 - 16/24 =r

First Step: 5x+−25= 4
1. addition property of equality
2.division property of equality
3.associative property of multiplication
4.distributive property of multiplication over addition
Answer:
Step-by-step explanation:
4 is the right answer
First step shows the "Distributive property of multiplication over addition"
What is distributive property of multiplication over addition ?
If we multiply a number by the sum of more than two, we use the distributive property of multiplication over addition.
Here the equation given is : 5(x+-5) = 4 ,
and, the first step is 5x=-25 = 4
which is obtained by the distributive property of multiplication over addition where, 5 is being multiplied with x and -5 respectively.
Therefore, Distributive property of multiplication over addition is the answer.

Write an equation to find the number of students in Mr. Boggs' homeroom if the total number of students is 90.
Teacher: Number of students
Mr. Boggs b
Mr. Hamilton 15(b+2)
Ms. Simpson 15
Mrs. Walton 2b-9
Answer:
15(b+2) + 15 + 2b-9 +b = 90
Step-by-step explanation:
Essentially you add up all of the values and make it equal to 90, then solve for b
15(b+2) + 15 + 2b-9 +b = 90
15b + 30 + 15 + 2b - 9 + b = 90
18b + 30 + 15 - 9 = 90
18b + 36 = 90
18b = 54
b=3
Find the midpoint of the line segment with end coordinates of: (−1,−6)and (4,5) Give coordinates as decimals where appropriate.
Answer: The coordinates of the midpoint (1.5, -0.5)
Step-by-step explanation:
For the x-coordinate, find the difference between -1 and 4. That's 5. Take half of 5 and add to -1. So -1+2.5= 1.5
For the y-coordinate, the difference between -6 and 5 is 11. Half of 11 is 5.5. Add -6 + 5.5= 0.5
