Respuesta :
(r-18)/15=9
Multiply both sides by 15 (r-18=135)
Isolate r (r=153)
The answer is r = 153
Multiply both sides by 15 (r-18=135)
Isolate r (r=153)
The answer is r = 153
i believe that r = 153
to check, 153 - 18 =135
135/15 = 9
so, therefore r = 153
to check, 153 - 18 =135
135/15 = 9
so, therefore r = 153
