Answer:
length = 17cm, width = 10cm
Step-by-step explanation:
2L + 2w = 54
L = w + 7
Substitute:
2(w + 7) + 2w = 54
2w + 14 + 2w = 54
4w = 40
w = 10
L = 10 + 7 = 17
Answer:
D
Step-by-step explanation:
Given V varies inversely as T, then the equation relating them is
V =
← k is the constant of variation
To find k use the condition, V = 12 when T = 6
k = VT = 12 × 6 = 72
V =
← equation of variation
Answer:
5
Step-by-step explanation:
K equals 3 and so 15/3 equals 5.
