Answer:
(
)
Step-by-step explanation:
The fastest way to do this is to convert both equations into slope-intercept form and graph it to find the solution point. If you wanted to do this algebraically, you might want to start out by getting rid of the fractions and using either substitution or elimination to find x and y.
You have to subtract 4 from 7 and then add 5 and 3 then add 8 and 2 then multiply 10 with 3 to get 30.
if 15 cars were washed there would be $52.50
Rational: (-15.333), (sqt of 400), (8.62134), (15 5/6), (-3 4/5)
Irrational: (sqt of 6), (pi), (sqt of 56), (sqt of 31)
