(WITH IMAGE) What is the value of m?

  10

Step-by-step explanation:

The two marked angles are a linear pair, so have a sum of 180°.

  (2m +10) +(5m +100) = 180

  7m +110 = 180 . . . . . . . collect terms

  7m = 70 . . . . . . . . . . . . subtract 110

  m = 10 . . . . . . . . . . . . . divide by 7

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
