Answer:
108
Step-by-step explanation:
Since angle AFB and angle BFC are next to each other and form a straight line, we can subtract 72 from 180 to get the missing angle measurement. (all straight lines add up to 180)
180-72=108
So 108 would be your answer

Answer:
-3
Step-by-step explanation:
Since the - in -7 and the subtraction sign - are the same, you have to group them so now it is + (positive). -10 + 7 = -3
We will use the equation:
r t = 3/4 r ( t+12 ) /:r
t = 3/4 t + 9
t - 3/4 t = 9
1/4 t = 9
t = 9 * 4 = 36 minutes ( takes a trip to the market )
36 + 12 = 48 minutes
The ride home takes 48 minutes.
