Question

If y=9.2 when x=6, how do you find x when y=3 given that y varies inversely as x?

Answer 1

`x = 18.4`

Explanation:

`y prop 1/x or y = k* 1/x or y*x = k or 9.2 *6 =k or k= 55.2 or y*x = 55.2`[k is constant for inversely variation equation ]

`y=3 ; x = ? y*x=55.2 or 3*x=55.2 or x = 55.2/3 = 18.4`[Ans]
