Kerry and luke biked a total of 18 miles in one weekend. kerry biked 4 miles more than luke. write s system of equations and solve it to find how far each boy biked.

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

25/4

step-by-step explanation:

call segment cd's length x. because dc and ab are parallel, angle acd and cab, so triangles adc and abc are similar and we can set up the equation x / ac = ac / ab, or x / 5 = 5 / 4 and x = 25/4.
