Answer:

7.5

Explanation:

0.2(6r-5) =8 Distribute.

0.2(6r)-0.2 (5) =8 Simplify.

1.2r−1 =8 Add 1 to each side.

1.2r =9 Divide each side by 1.2.

1.2r/1.2 =9/1.2 Simplify.

r =7.5

Hope this helps!

0.2(6r - 5) = 8
1.2r - 1 = 8 ( by distributing 0.2 )
1.2r = 8 + 1( by adding 1 )
1.2r = 9 ( dividing 1.2 on both side )
r = 7.5 Ans
