Answer: 55
Step-by-step explanation:
D=m/v
D=14.4
M=792
V= unknown
14.4=792/v- multiply both sides by V
V • 14.4=792-divide both sides by 14.4
V=55
(1/15) / (1/3) = 1/x
cross multiply
1/15x = 1/3
x = 1/3 * 15
x = 15/3
x = 5 hrs
Answer:
a₁ = -28
aₙ = a₁ + 12 (n-1)
Step-by-step explanation:
a₁ = -28
a₂ = -28 + 12 (2 - 1) = -16
a₃ = -28 + 12 (3 - 1) = -4
a₄ = -28 + 12 (4 - 1) = 8
aₙ = a₁ + 12 (n-1)
Last one is the correct answer
