Assume that y varies inversely as x. If x = 12 when y = 9, what is x when y = -3? 108 -36 27 -4 Assume that y varies inversely with x. If y = 3.75 when x = 9, what is x when y = 6.75? 33.75 1.8 5 60.75 Use the Law of Levers to solve the problem, x1y122. The number of chairs in a row varies inversely as the distance between them. When they are 10 centimeters apart, 27 chairs fit in a row. If 30 chairs are needed in a row, how many centimeters apart should they be placed? 9 cm 12 cm 15 cm 8 cm
