Asked by LD

as the weight held by a spring increases, the length of the spring increases proportionally. Suppose a 2-lb weight stretches a spring to 15 in., and a 12-lb weight stretches the same spring to 20 in. What is the length of the spring with no weight attached?
Answered by drwls
(20-x)/(15-x) = 12/2 = 6
90 - 6x = 20 - x
5x = 70
x = 14 inches
