Answer:
Problem 1:
x=12, x=3, x=6
Problem 2:
18*3=54
54/18=3
Problem 3:
Part A: 36/4.5=? 4.5*x=36
Part B: 8
Step-by-step explanation:
Answer:
The length is 6 feet and the width is 4 feet
Step-by-step explanation:
Let x represent the length of the yard
The width can be represented by x - 2, since it is 2 less than the length.
Use the perimeter formula, P = 2l + 2w, where l is the length and w is width
Plug in the expressions and perimeter:
20 = 2x + 2(x - 2)
Solve for x:
20 = 2x + 2x - 4
20 = 4x - 4
24 = 4x
6 = x
So, the length is 6. Plug this into x - 2 to find the width
x - 2
6 - 2
= 4
So, the length is 6 feet and the width is 4 feet
The answer would be n = 1
If you're solving for a, you would add 32 to both sides
2a=32
then you would divide by 2
a=16
