Answer:

50

Step-by-step explanation:

Since M is the midpoint of XY, this means that XM and MY must be equivalent from the definition of midpoint.

So:

[tex]XM=MY[/tex]

The entire length of the segment (XY) is:

[tex]XY=XM+MY[/tex]

We know that XM is equivalent to MY. Substitute MY for XM:

[tex]XY=MY+MY[/tex]

Combine like terms;

[tex]XY=2MY[/tex]

We are told that YM (or MY) is 25. So:

[tex]XY=2(25)[/tex]

Multiply:

[tex]XY=50[/tex]

So, the length of XY is 50.

And we're done!

50?

X_________M__________Y

2x + 5 = 25

x = 10 so 2(10) + 5 = 25

25 + 25 = 50
