∠A and \angle B∠B are complementary angles. If m\angle A=(6x-8)^{\circ}∠A=(6x−8) ∘ and m\angle B=(5x+21)^{\circ}∠B=(5x+21) ∘ , then find the measure of \angle B∠B.

In a certain pentagon, the interior angles are a,b,c,d,e where a,b,c,d,e are integers strictly less than 180. ("strictly less than 180" means they are "less than and not equal to" 180.) if the median of the interior angles is 61 and there is only one mode, then what are the degree measures of all five angles?

Which equation represents the function on the graph?

Mason and christian go to the movie theater and purchase refreshments for their friends. mason spends a total of $45.75 on 3 bags of popcorn and 6 drinks. christian spends a total of $71.50 on 6 bags of popcorn and 4 drinks. write a system of equations that can be used to find the price of one bag of popcorn and the price of one drink. using these equations, determine and state the price of a drink, to the nearest cent.
