Atotal of 396 tickets were sold for the school play. they were either adult ticket sor student tickets. the number of student tickets sold was three times the number of adult tickets sold. how many adult tickets were sold

The answer would be 97 adult tickets.  

Step-by-step explanation:

Number of adult tickets sold = x  

Number of student tickets sold = 3x

(example: 3 times the number of adult tickets sold)  

total tickets sold = 3x +x = 4x = 388(given)  

=> x = 388/4 = 97

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.
