6cm object is 15 cm from a convex lens that has a focal length of 5 cm. what is the distance of the image from the lens, to the nearest hundredth?

The distance of the image from the lens is 7.5 (7.5 = 1 / (1/5-1/15) cm. This problem can be solved using the converging lens formula for the distance which is the 1/f = 1/do + 1/di formula where f is the focal length, do is the object's distance to the lens, and di is the image's distance from the lens.
