First car is x
second car is y
25x+30y=1550
x+y=55
Multiply the second equation by -25 for elimination method to cancel out x
-25x-25y=-1375
Add the two equations
5y=175
y=35
Plug this value into the second equation
x+35=55
x=20
Final answers:
First car=20 gallons
Second car=35 gallons

Answer:
Step-by-step explanation:
The chart doesn’t make much sense. I don’t know why some boxes are complete empty.
Log₃(60) = log₃(6) + log₃(10) = log₃(3) + log₃(20) = log₃(120) - log₃(2) = log₃(240) - log₃(4)
log₇(36) = log₇(18) + log₇(2) = log₇(9) + log₇(4) = log₇(72) - log₇(2) = log₇(144) - log₇(4)
log₆(18) = log₆(9) + log₆(2) = log₆(6) + log₆(3) = log₆(36) - log₆(2) = log₆(54) - log₆(3)
log₂₅(60) = log₂₅(30) + log₂₅(2) = log₂₅(15) + log₂₅(4) = log₂₅(180) - log₂₅(3) = log₂₅(300) - log₂₅(5)
log(40) = log(20) + log(2) = log(8) + log(5) = log(80) - log(2) = log(120) - log(3)
