A school reserved a banquet hall for the spring dance. In addition to a $100 deposit, each couple must pay $20. If the total cost of the banquet hall is $1, 140. Solve the problem arithmetically. Show the steps you used.

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.

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
