I'm confused on how to do 47 and 50.

47. Divide each side by one half times h. Then subtract b1 from each side. You'll get A/(1/2h)-b1=b2. (A divided by 1/2h - b1 =b2)

50. Divide each side by one half times s. Then subtract s squared from each side. You'll then get V/(1/2s)-s^2=h. (V divided by 1/2 times s - s^2 = h)

The regular price of 1 pizza is 13 dollars because $48 + the $4 off is $52 and that divided by 4 pizzas is $13! vote me brainliest please ❤️
