What is the length of the missing part 13ft 5ft b

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.

Solve for x and y: 217x + 131y = 913; 131x + 217y = 827

Which number line correctly shows 0.8 + 0.3?
