Question 122375: I need to solve with a system of linear equations and I don't know how to write the equation.
The new parking lot has spaces for 450 cars. The ratio of spaces for full-sized cars to compact cars is 11 to 4. How many spaces are for full-sized cars? How many spaces are for compact cars?
I just need the equation. thanks!
Answer by scott8148(6628) (Show Source): You can put this solution on YOUR website!
let x="compact spaces", so 450-x="full-size spaces" __ (450-x)/x=11/4
"cross multiplying" __ 4(450-x)=11x __ 1800-4x=11x __ 1800=15x
