32 + 0.75x = 47
0.75x = 47 - 32
0.75x = 15
x = 15 / 0.75
x = 20 <=== 20 minutes
The answer is B. Hope this helps!

Answer:
-5/7
Step-by-step explanation:
We need to find g(7) first
All we have to is plug 7 in the place of x
g(7) = 1/7
Now we have f(1/7) = 2x - 1
f(1/7) = 2(1/7) - 1
f(1/7) = 2/7 - 1
Don't forget about common denominators
2/7 - 7/7 = -5/7
