Answer:
A: 68.25 minutes
B: 12 times
C: 42 mins and you decide this part I actually don't know. But I think it could be reasonable, after 40 times someone should get pretty good at it.
Step-by-step explanation:
a: 72 -0.75*5 = 68.25
b: M=63=72-0.75n
subtract 72 from each side: -9 = -0.75n
divide each side by -0.75: n = 12
so 12 times
c: 72 - 0.75(40) = 42 minutes. Now this could be is reasonable, but we don't know what their desert is. But 40 times is a lot of practice.
The answer is B) Two times the sum of a number and two. That would be completely different that twice a number plus two.
Hope this helps!

-4x/-4=4/-4
x=-1
Actual W/ actual height= model W/ model height
55 ft/ actual height= 1.5 in./ 15 in,
actual height=55 ft*15 in./1.5 in= 550 ft
