Answer:
17. 42
18. 12
19. 12
20. 12
Step-by-step explanation:
Simply substitute the given values into the variables. So if m = 6 and n = 2:
7m = 7(6) = 42
6n = 6(2) = 12
mn = (6)(2) = 12
3m - 6 = 3(6) - 6 = 18 - 6 = 12
1956/(3+1)=489 adult tickets cost for all adults
1965-489= 1467 cost of child tickets
1467/5.30=276.8
277 child tickets were sold.
2/5=4/10=12/30 1/3=10/30 12/30+10/30=22/30 22/30=11/15
