Yis inversely proportional to x and that y = 37 when x =72. find y when x = 12

 y = 222

Step-by-step explanation:

y inversely proportional to x means:       x · y = k

where k is the constant of proportionality

Step 1: Find the k-value

x · y = k

72 · 37 = k

2664 = k

Step 2: substitute k = 2664 and x = 12, then solve for y

x · y = k

12 · y = 2664

     y = 222      divided both sides by 12
