Answer:
see explanation
Step-by-step explanation:
let w represent the width then length = w + 7
The perimeter of the rectangle = 2w + 2(w + 7) = 2w + 2w + 14 = 4w + 14
The perimeter is given as 54 m, thus
4w + 14 = 54 ( subtract 14 from both sides )
4w = 40 ( divide both sides by 4 )
w = 10
Thus
width of playground = w = 10 m
length of playground = w + 7 = 10 + 7 = 17 m
Answer:
x= -1
Step-by-step explanation:
First, distribute the -3 through the parentheses
4x-8= -3(2x+6)
= 4x-8= -6x-18
Second, move the variable to the left-hand side and change its sign
4x+6x= -18+8
10x= -10
Divide both sides by 10
x=-1
Answer:
12 and 13
Step-by-step explanation:
The computation of the number of ounces will each person serving be is given below:
Ounces be 64
And, the friends be 5
So for each one it would be
= 64 ÷ 5
= 12.8
That means
12.8 is lies between 12 and 13
I believe it’s 512$
1/4 of 512 is 128
128 * 4 = 512
