Answer:
16. r(s)(t) =
r=2, s=3, t=4
(2)(3)(4)=
(2*3) = 6 ---> 6(4) = 24
final: 24
17. (r)(s)(t)(x)(y) =
r = 2, s = 3, t = 4, x = 5, y = 6
(2)(3)(4)(5)(6)
2*3=6
6*4=24
24*5= 120
120*6=720
final: 720
18. (7x + 2Y) =
x = 5, y = 6
rewrite---> = [7(5) + 2(6)]
[35 + 12] = 47
final: 47
hope this helpsss sorry took a while LOL
Step-by-step explanation:
q = 1; r = 2; s = 3; t = 4; x = 5; y = 6
Answer:
C
Step-by-step explanation:
Use the equation 
Input the numbers----> 
Simplify ----> 
Find the square root------->
You can first make the equations:
6x+4y=548
y-12=x
Here, you can use the substitution method and you get:
6(y-12)+4y=548
6y-72+4y=548
10y=620
y=62
Then there are 62 student tickets and 50 adult tickets.
