Tony ran laps around a track to raise money for a hospital. tony raised $15 plus $1.50 per lap that he ran. he raised a total of $255.00. let x represent the number of laps tony ran. what expression completes the equation to determine the total number of laps tony ran? how many laps did tony run?

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
