Answer:

x=9

Step-by-step explanation:

First, midpoint means “the middle” so that mean that segment AB is half of AC. You can make an equation: 5x+18=4.5+6.5x. After that, you have to move the numbers on one side and the variables on the other.

You then come up with 13.5=1.5x

Divide both of them by 1.5 and then you get x=9

Answer:

X=9

Step-by-step explanation:

Okay first Hello! :)

so, B is the mid point of the segment midpoint means the half way

so, if AB= 5x+18 is the half to get the whole you would need to times it by 2

you get 10x+36

so now you equal them together

10x+36= 13x +9

Always move your smaller x, and now you got

3x+9=36

move your 9 over and switch the sign you get

3x=27

divide by three and you get

X=9
