I NEED HELP PLEASE IM BEGGING YOU PLEASE I NEED HELP WITH THE ONES THAT A HIGHLIGHTED PLEASE

 r = 6

Step-by-step explanation:

64= 8(r+2)

64/8  = 8(r+2) / 8  divide both sides by 8

    8 = r + 2       The eights cancel out

- r = 2 + 8         Move the variable to the left and change its sign

- r = - 6             to get id of the negative -r make  the 6 a positive

 r=6

-4(r + 6) = -63

- 4r - 24 = -63    Distribute 4 through ( ) -4 x4  -4 x6

-4r =63 + 24      Move -24 to the right (making it a positive )

-4r = 39

-4r / -4 = 39 /4  divide both sides by -4

r= 39/4  

4444444444444 i think

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hope i
