What is the range for the amount of hours studied? 6 18 4 12

6

Step-by-step explanation:

You take the most amount studied (18) and the least amount studied (12) and subtract them and that would be the range

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°
