Answer:  [B]:  -3 .
______________________________________________________
Explanation:
______________________________________________________
Given:
__________________________________________
  "  -15r – 8 = 37 " ;   Solve for " r "  ;
__________________________________________
     →  Add  "8" to each side of the equation ; 
__________________________________________
     →  -15r – 8 + 8 = 37 + 8 ; 
__________________________________________
to get:
__________________________________________
     →  -15r  =  45 ;
__________________________________________
     → Divide EACH side of the equation by "-15" ; to isolate the variable, "r", on one side of the equation; and to solve for, "r" ; 
___________________________________________
     →  -15r / -15  =  45 / -15 ;
___________________________________________
          →   r  =  - 3  ; which is our answer; 
________________________________________
          →   which is:  Answer choice:  [B]:  "-3" .
