A worker at a snack stand opened a new box of cups. The first day, the worker used 30 cups from the box. The second day the worker used 15% of the remaining cups in the box. A total of 90 cups were used on the second day. What was the original number of cups before any cups were used? This is a multi step word problem.

Step-by-step explanation:

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

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°
