Answer:
rational number
Step-by-step explanation:
Distribute
2z-1=z+8-2z
add like terms
2z-1=-z+8
add z to both sides
3z-1=8
add 1 to both sides
3z=9
divide both sides by 3
z=3
Answer:
60
Step-by-step explanation:
p = 180 - [ 360 - ( 130 + 110 ) ]
= 180 - [ 360 - 240 ]
= 180 - 120
p = 60
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.)
