Question

If dm=50 what ia the value of r?

Answer 1

15

Explanation:

Given:

• DG = r + 3
• GM = 4r - 28
• DM = 50
• r = ?

Solution:

• DM = DG + GM
• r + 3 + 4r - 28 = 50
• 5r - 25 = 50
• 5r = 50 + 25
• 5r = 75
• r = 75/5
• r = 15

Answer 2

r = 15

Explanation:

Line segments DG and GM add up to DM:

r + 3 + 4r - 28 = 50

5r - 25 = 50

5r = 75

r = 15
