Question

M) Point K is the midpoint of JL. JK = 6x + 9 andKL = 5x + 12. Find JK.1) 272) 303) 18

Answer 1

The right option is 1) 27

Step-by-step explanation:

According to the given data we have the following:

K is the midpoint of JL.

JK = 6x + 9

KL = 5x + 12

K is the midpoint of JL, hence, JL=JK+KL

So, to find JK we would equal JK with KL

So, 6x + 9=5x + 12

6x-5x=12-9

x=3

Therefore, JK=6(3)+9

JK=18+9

JK=27

Therefore, the right option is 1) 27
