Answer:
First car: 30 gallons
Second car: 20 gallons
Step-by-step explanation:
Mark first car used gallons x, and second car used gallons y.
In total they consumed 50, so x + y = 50
In total they went 1050miles, so 15*x+30*y=1050
We get a system of equations. Solve the system.
Take first equation and solve x. x = 50 - y
Then insert x to second equation.
15*(50-y)+30*y=1050
750-15y+30y=1050
15y=1050 divide both sides by 15
y=20 gallons Found y.
Find x from x=50-y
x=50-20=30 gallons
Oh it’s d I did this before
