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
The equation for the line of reflection is x = 2.
If you drew a vertical line crossing the x-axis on x = 2, the drawing will be the same on the left and right side, as if one side was drawn then exactly copied on the other side but flipped.
The figure is symmetrical, and x = 2 is the line of symmetry.

Step-by-step explanation:
Answer:
21/2
Step-by-step explanation:
(x-8)/5=2/4
step 1 you simplify if you can to make it easier
(x-8)/5=1/2
step 2 multiply each side by 5
x-8=5/2
step 3 add each side by 8
x=5/2+8
16/2+5/2=21/2
x=21/2
