The total number of couples attending the banquet was 52.
Step-by-step explanation:
Given that a school reserved a banquet hall for the spring dance, and that, in addition to a $ 100 deposit, each couple must pay $ 20, to determine the total number of couples attending if the total cost of the banquet hall was $ 1,140 is due perform the following calculation:
100 + (20 x X) = 1140
20X = 1140 - 100
X = 1040/20
X = 52
Thus, the total number of couples attending the banquet was 52.
you have -8 and twelve you equation is x -12 = -8 so we just have to flip the equation around to make it x = 12 -8 which is easy . You just have to make sure you don't get mixed up while flipping the signs.
