Jim takes 2 times as long as Rosa to clean the garage. Working together, they can clean the garage in 8 hours. How long does it take Jim and Rosa to clean the garage if they work alone? [For full credit, set up an equation and solve it.]

Will give are given that xy is parallel to zw. if xz is a transversal that intercepts xy and zw, angle angle alternate interior angles. since xy is parallel to zw, we know that these angles are we also know that angle xvy and angle zvw are , and thus congruent. we can conclude that △xyv ~ △zwv using the similarity theorem.
