R would equal -4. Subtract 7 from each side & youll get -12=3r then divide each side by 3.

Hi!

-5 = 7+3r

-5-3r = 7+3r-3r

-5-3r = 7

-5-3r+5 = 7+5

-3r = 12

-3r 12
▬ = ▬
-3 -3

r= -4

The answer is -5, -5 added by 5 cancels each other out. Then when you add 4x + 8x, you get 12x. So when you do 12x= -60, you get -5.

X^3 -4x^2 +7x -28 = x^2(x-4) +7(x -4) = (x^2 +7)(x-4)

so the 4th choice will be right sure

0.05/1 min * 60 min = 0.05 * 60 = 3

<em>Therefore, the unit rate per hour is $3.</em>
