Question

Find AM, if AM = 6y-4 and MC = 2y+12.

Answer 1

Answer: 20

Step-by-step explanation:

Since Line l is a segment bisector, we know that AM and MC are equal to each other.

6y-4=2y+12        [subtract both sides by 2y]

4y-4=12              [add both sides by 4]

4y=16                 [divide both sides by 4]

y=4

Now that we have y, we plug that into AM.

6(4)-4                 [multiply]

24-4                   [subtract]

20

Now, we know that AM is 20.
