## anonymous 5 years ago The distance a spring will stretch varies directly with how much weight is attached to the spring. If a spring stretches 9 inches with 100 pounds attached, how far will it stretch with 90 pounds attached? Round to the nearest tenth of an inch. HELP please (:

let x for how far$\frac{9}{100}=\frac{x}{90}$ coss and time 9*90=100x x=810\100 x=81
