Three hours after the bus starts out, it's 150 miles ahead of the truck. Then the truck starts out, and it gains (65-50)=15 miles on the bus every hour. If neither of them ever stops for anything, the truck will catch up to the bus in ( 150/15 ) = 10 hours. . . . (The hint is useless.)
The answer is c, 2 1/2 miles
Answer:
the sustitucion metod is easy x=5 y=3
Step-by-step explanation:
x-3y=-4 (-2)
2x-y=7 (1)
-2x+6y=8
2x-y=7
5y=15
y=3
2x-3=7
2x=10
x=5
We can factor a 12 out of both terms. This leaves us with the expression 12(3x + 1), which is equivalent.
