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
A (-7,5) . B (10,9) . C (-4,-11
5.5 miles
88 divided by 16 = 5.5
