Aparking meter in downtown seattle takes dollar coins and quarters only. when the machine was last emptied, there were 250 coins in it, with a total value of $137.50. which of the following systems of equations gives the number of quarters, q, and the number of dollar coins, d ? a. d + q = 250 and 100d + 25q = 137.50 b. d + q = 250 and 0.1d + 0.25q = 137.50 c. d + q = 250 and d + 0.25q = 137.50 d. d + q = 137.50 and d + 0.25q = 250 e. d + q = 137.50 and 100d + 25q = 250 question 2 of 3 for two consecutive integers, the result of adding double the smaller integer and triple the larger integer is 153. what are the two integers? f. 29, 30 g. 30, 31 h. 49, 50 j. 50, 51 k. 76, 77 question 3 of 3 in a certain triangle, the longest side is twice as long as the shortest side, and the shortest side is 4 inches shorter than the middle side. if the perimeter of the triangle is 52 inches, how long is the longest side? a. 10 inches b. 12 inches c. 16 inches d. 20 inches e. 24 inc
