Answer:

r = 8

Step-by-step explanation:

15 = 1.5r+3

Subtract both sides of the equation by 3.

15-3 = 1.5r+3-3

12 = 1.5r

Divide both sides of the equation by 1.5.

12/1.5=1.5r/1.5

8 = r

r = 8

Answer:

[tex]8[/tex]

[tex]1.5r + 3 = 15 \\ 1.5r = 15 - 3 \\ 1.5r = 12 \\ r = \frac{12}{1.5} \\ r = \frac{120}{15} \\ r = 8[/tex]
