Which equation could be used to solve the question below? tirza has b books. her mom has 35 books and her sister has 24 books. they have 83 books in all. how many books does tirza have? a. b + 35 + 24 = 83 b. b - 35 + 24 = 83 c. b + 35 - 24 = 83 d. b - 35 - 24 = 83

The answer would be option A. Because nobody in Tirza's family has a negative amount of books (is that even possible?) B, C, and D are incorrect.

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°
