Question

Point M is the midpoint of segment AB. If AM = 50 – 3x and MB = –20 + 4x, find the value of AM

AM = -10
AM = 10
AM = -20
AM = 20

Answer 1

AM = 20

Explanation:

AM = 50 - 3(10)

AM = 50 - 30

AM = 20

Answer 2

Point M is the midpoint of segment AB

AM = MB

50 - 3x = –20 + 4x

7x = 70

x = 10

AM = 50 - 3(10)

AM = 50 - 30

AM = 20

Answer

AM = 20
