Atotal of 363 were sold for the school play. they were either adult tickets or student tickets. the number of student tickets sold was two times the number of adult tickets sold. how many adult tickets were sold?

The number of adult tickets sold was 121

Step-by-step explanation:

The general equation is: S + A = T    ;where S means student tickets, A means adult tickets and T means total tickets. We know that S is two times A and T is 363. So, S will be 2x and A will be x. Then, the new equation is 2x + x = 363.

S + A = T  

2x + x = 363  

3x = 363  

x = 363 / 3

x = 121

Adult tickets: A = x = 121

Student tickets: S = 2x = 2 * 121 = 242

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
