The music room contains 4 rows of 6 chairs. ariana was asked to put the chairs in 3 rows. how many chairs will be in each row?

8

Step-by-step explanation:

4 x 6 = 24

3/24 = 8.

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°
