Answer:
9.6 miles
Step-by-step explanation:
Let x represent the round trip distance. Then Michelle's time was ...
t = distance/speed
1 = (x/2)/8 +(x/2)/12 = x(1/16 +1/24) = x(3/48 +2/48) = x(5/48)
48/5 = x = 9.6
The round trip is 9.6 miles.
-2k - (-7)k
= -2k + 7k
= 5k
-7(p + 2) + 9(p - 4)
= -7p - 14 + 9p - 36
= 2p - 50
