The equation has no solution because:
5(n+10)=5n+10n
5n+10n=5n+10n
I subtract 5n from both sides
10n=10n
Only one side is supposed to have the variable which is n, so the equation has no solution.
Equation of straight line is y=mx+c ,here m is slope in given question m is 1/4.
Hope it helps you.
Hi!
I think Grace needs to wash at least 6 cars. Please tell me if I'm wrong.
Thank you
That would be 35 + 0.20*35 = $42
