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 answer is d hope this helps

Answer:
$52.11
Step-by-step explanation:
23.16÷4=5.79
5.78×9=52.11
To find the area of the deck, we need to calculate the area of triangle and rectangles
Lets find the area of triangle A
Area of triangle = 
base = 9 and height =10
So area of triangle A =
= 45
Area of rectangle = Base * height
Base of rectangle B = 9ft
Height of rectangle B = 12ft
Area of rectangle B = 9*12 = 108 square feet
Base of rectangle C = 24ft
Height of rectangle C = 22ft
Area of rectangle C = 24 * 22 =528 square feet
Area of the deck = Area of A + area of B + area of C
= 45 + 108 + 528
= 681 square feet
