Answer:
Total cost to carpet the living room is $8,512.
Step-by-step explanation:
Living room size = (4*1/4*16)*(7*1/4*16) = 16 ft * 28 ft = 448 sq/ft
Cost = 19 * 448 = $8,512.
Your answer should be 19>n+3
42 firefighters in total.
16 volunteered for the special rescue team.
n + 16 = 42
or it could be this way:
42 - 16 = n
Answer:
Step-by-step explanation:
perimeter of a rectangle = twice the length plus twice the width
P = 2L + 2W equation 1 P = 86 ft
Given the length is seven feet more than the width
L = W + 7 equation 2
Substitute equation 2 into equation 1
P = 2(W+7) + 2W = 86 ft
2W +14 + 2W = 86 ft
4W = 86 - 14
W = 72 / 4
W = 18 feet
