Question

Can someone help asap

Answer 1

Part A:

Expression: 21 = 8h + 179

Part B:

21 = 8h + 179

h = - 19

Move 179 to the other side by subtracting 179 from both sides.

21 - 179 = -158

-158 = 8h

Then, divide both sides by 8 to get the feet descended per hour.

-158/8 = -19

h = -19

Therefore, Luther and Nicole descend approximately 19 feet per hour.
