A car service charges customers a flat fee per ride (which is higher during rush hour traffic) plus charges for each minute and each mile. Suppose that, in a certain metropolitan area during rush hour, the flat fee $2, the cost per minute is $0.40, and the cost per mile is $1.30. Let x be the number of the minutes and y the number of miles. At the end of the ride, the drive said that the passenger owed $25.10 and remarked that the number of minutes was five times the number of miles. Find the number of the minutes and the number of miles for this trip

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.
