Which one of the following numbers is a multiple of 8?

a. 512
b. 98
c. 124
d. 27

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality

step-by-step explanation:

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°
