Fran is limited to watching television less than 12.8 hours per week. she has already watched 4.8 hours, and each show is 0.8 of an hour long.

0.8x + 4.8 < 12.8

how many more shows can fran watch this week?
a. x < 4.8
b. x < 8
c. x < 10
d. x < 0.8

what is all that apply?

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°
