Answer:

Step-by-step explanation:

x= # of hikes

3x +16 =5x

-3x. -3x

16=2x

16/2= 8

2x/2= x

8=x

x=8

check:

3(8) +16 =5(8)

24 +16 =40

40=40 ✓

there for at 8 hikes with either deal it would be the same but if you went up a number of hikes for the first option it would only be $43.00 spent in total. but with the second option it would be $45.00.

Use the formulla d=rt.find t for r =48.3m/h and d=545.79m.

jenyasd209 [6]

If you solve d = rt for t, you have t = d/r. If we have values for d and r we will fill them into that equation and divide. $\frac{545.79m}{48.3 \frac{m}{h} }$ . Setting that up so the meters cancel as they should looks like this: $545.79m* \frac{h}{48.3m}$ lets us divide as we need to and at the same time cancel out the distance, leaving us time in hours. The t value then is 11.3 hours.
