A conjecture and the two-column proof used to prove the conjecture are shown. Given: S is the midpoint of segment R T. Segment R
T is congruent to segment X Y. Prove: segment R S is congruent to segment X Y. Segment X Y with endpoints X and Y. Line R S T is horizontal. Line R S T has two segments R S and S T with the same length. S is the midpoint and R and T are the extreme left and extreme right points respectively. Drag an expression or phrase to each box to complete the proof.
(I'm assuming there is a mistype in the question,where it says RT is congruent to segment XY, I suppose it was ST is congruent, otherwise RS cannot be congruent to segment XY)
5p + 2(p + 4) .......because pencil cases (p) sell for 5 bucks a piece....and mechanical pencils (p + 4), sell for 2 bucks a piece. She is basically selling 4 more mechanical pencils then she is pencil cases.
