Question

Can someone help me pls

Answer 1

A line segment bisector passes through the midpoint of the segment.  So the segment bisector of JK is M.

Also, the length of JM is 7x + 5, which we know is equal to 8x, so we just have to find x and then figure out the length.

7x + 5 = 8x   subtract 7x from both sides

5 = x

Does it work? Let's see. 7(5) + 5 = 40  AND  8(5) = 40

The length of JM is 40.
