Let h represent hamburgers and c represent cheeseburgers. We can set up an equation:
h + c = 437
h + (h - 63) = 437
h + (h - 63 + 63) = 437 + 63
h + h = 500
2h = 500
2h / 2 = h
500 / 2 = 250
h = 250
250 hamburgers were sold.
To find how many cheeseburgers were sold, we subtract 250 - 63:
250 - 63 = 187
187 cheeseburgers were sold.
187 + 250 = 437
250 hamburgers and 187 cheeseburgers were sold on Thursday.
21. D. is the answer. Angle Q is 75 degrees. X=30. The triangle is an isosceles angle so therefore there are 2 angles are congruent to each other, Angle R and Angle Q. All three of the angles should add to 180 degrees.
Hi there! 5 bottles of water for $3 would make $0.60 per bottle. 0.6 * 15 = 9. That means 15 bottles of water should equal $9, but instead it is $8. Based on that, no. The costs for bottles of water is not proportional to the numbers sold. Basically, you can divide to find unit prices and multiply the number of another item to see if the numbers are proportional.
