Hello!
Let 'a' stand for adult tickets and 'c' for children tickets.
a + c = 15
(Both adult and children tickets make up a total of 15 tickets).
30a + 20c = 330
a = 3
c = 12
A N S W E R:
William bought 3 adults tickets and 12 children's tickets.
I believe C is correct,
Also, did you finish the equation for letter D?
The answer is 9 because 3/5 to second power is 9/25 then you multiply it by 25 and you get 9
Answer: 405 yd squared
Step-by-step explanation:
V = (bh)/2
b = (15 x 9)/2 = 67.5
67.5 x 12 = 810
810/ 2 = 405
