3 goes into 51 and 9 evenly because if you divide 51 by 3, you'll get 17 and if you divide 9 by 3, you'll get 3.So 3 is the answer to the question.
Answer:
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.
Answer: 11/-10
Why?

12-1 / -19+9= 11/-10
So the slope is 11/-10
