Answer:
x = 6, BC = 60
Step-by-step explanation:
6x + 2x + 1 = 81
8x + 1 = 81
8x (+ 1 - 1) = 81 - 1
8x = 80
8x/8 = 80/8
x = 10
6x
6(10) = 60
A rock climber's elevation above sea level changed −82 1/2 feet in 2 1/4 minutes as she descended.
so the the climber's average change in elevation per minute was:
x = -82 1/2 / 2 1/4x = (-165/2) / (9/4)x = (-165/2) x (4/9)x = -18 feet per minute is his change in elevation

Answer:
Step-by-step explanation:
69 + 15h = 39h
69 = 39h - 15h
69 = 24h
69/24 = h
2.875 hrs <======
69 + 15(2.875) = 39(2.875)
69 + 43.125 = 112.125
$ 112.125 = $ 112.125 <====
I didn't round anything.
