Wait so what is the point of this question?
Kerry and Luke biked a total of 18 miles in one weekend. Kerry biked 4 miles more than Luke. How far did each bike? Write a system of equations and solve.
let x - kerry y - luke x + y = 18 x = y +4 y + 4 + y = 18 2y = 14 y = 7 x = 11
Triangle's angles add to 180:
99 + 3x + x + 5 = 180
4x = 74
x = 18.5
A, c, and e i believe have a good day (:
