Krysta took a total of 36 quizzes over the course of 6 weeks. After attending 7 weeks of school this quarter, how many quizzes will Krysta have taken in total? Assume the relationship is directly proportional.

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°
