Answer:

R = 3.6

A = 2

Step-by-step explanation:

R is inversely proportional to A

....which means that....

; R = k/A.....(where k is a constant that does not change)....

;If R = 12 and A = 1.5....then k = 18..

obtain k,by substituting the values into the equation...k = RA

a) If A = 5....then R = 18/5....

; Ans..., R = 3.6

b) If R = 9....then A = 18/9

;Ans..., A = 2
