If m is the midpoint of segment JK, JM equals 7x minus 32, and MK equals 89 minus 4x, what is MK?

KonstantinChe [14]

Step-by-step explanation:

Imagine this segment, given that m is the midpoint of segment JK...

J________M________K

JM = 7x-32 MK = 89 - 4x (given)

If m is the midpoint, then JM and MK are the same lengths (equal to each other). We can use that to first find what x is.

$7x -32 = 89 - 4x\\$

Steps to find x (we have to get x by itself):

$7x - 32 + 4x = 89 - 4x +4x$

$11x -32 = 89$

$11x -32 +32 = 89 +32$

$11x = 121$

$\frac{11x}{11} = \frac{121}{11}$

$x=11$ (we haven't found the answer yet! we only found x)

Now that we found x, we can find segment MK. Now we know that:

$MK = 89 - 4x$

$x= 11$

Let's plug x into the equation:

$MK = 89 - 4(11)\\MK = 89- (44)\\MK = 45$

Answer: $MK= 45$
