Answer:

The value of r is 12.

Step-by-step explanation:

Since DM = 25, and DG + GM = DG, we can use this information to compose the equation:

r + 2 + 2r - 13 = 25

Combine like terms by adding r and 2r, and subtracting 2 and 13.

3r - 11 = 25

Add 11 to both sides.

3r = 36

Divide both sides by 3.

r = 12
