a) Write an algebraic expression to represent the situation.
b) This Friday, Tobias will work for 9 hours. Use the expression from part (a) to figure out
how much money Tobias will make.

13 is going to be the answer #biden 2020 btw

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°
