Mr. patterson ordered pizzas for the soccer team. medium pizzas have 8 slices and large pizzas have 10. if there are 13 pizzas and 108 slices, how many of each size pizza were ordered?

M + l = 13 [m = 13 - l]

8m + 10l = 108

8(13 - l) + 10l = 108
104 - 8l + 10l = 108
2l = 4
L = 2

M = 13 - 2 = 11

There are two large pizzas and eleven medium pizzas.

29. because you will divide each number of months by 12 to find the number of years. which would mean, 5, 12.5, 16, 45, 50, 72.5. which is crazy. anyhow, i think you find the median in the middle. and yea hope your test goes good
