The correct answer is C
The 5 times means we need to do 5j using multiplication, and the 4 more means we need to add 4
So the answer is 5j+4
Hope this helps
You have to plug in the numbers for x and then solve.
For example, when it says y=2x-4, you put -2 and the numbers below it for x and then solve.
(I don't want to give you the answer to everything and want to help you understand how to do it.)
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
