Question

K is the midpoint of JL,JL =4x-2, and JK=7. Find x,KL, and JL.

Answer 1

if K is the midpoint of 4x-2, that means it's halfway on the line, right?

Answer 2

that's the same as saying that from one end (J, in this case) to K is half of 4x-2.

Answer 3

Which means that JK is 2x-1. now we know JK = 7, so 2x-1 = 7. if we solve that we get x = 4.

Answer 4

KL is the same as JK, and we know that JK = 7, so KL = 7.

Answer 5

now that we know x = 4, we can find JL (4x-2). after you do the math, you get 14. So x = 4, KL = 7, and JL = 14.
