Annie graphed how many books in the school library are about her favorite subjects.

Alice has read 10 of these books (from the graph above)

How many books about Alice’s favorite subjects that she has not read are in her school library?

100

Step-by-step explanation:

25+15+30+40-10=100

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°
