what is the value of x satisfies the equation 3( x +7 ) =18
Answers
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.

Answers
Answer:
b
Step-by-step explanation:
4 2/3= 12/3+2/3=14/3
3 2/1=7/2 but you have to flip it
so you end up with 14/3*2/7
4 2/3 = 14 / 3
3 1/2 = 7/2
An easy way to divide fractions is to find the reciprocal of the second fraction.
The reciprocal of 7/2 = 2/7
Then we multiply straight across.

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.

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.
Answers
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.
