Which expression has a solution of 12, if m = 7?

5 - m
m + 5
m - 5
m + 7

the reporter's right

step-by-step explanation:

1/4 = .25 / 25%

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
