Answer:
8 child tickets and 4 adult tickets.
Step-by-step explanation:
8c + 11a = 108
8x + 11y = 108
Lets graph it.
When we graph, we find that there it crosses at 2 whole numbers: (8, 4).
So there were 8 child tickets and 4 adult tickets.
We can check our work by doing 8(8) + 4(11) = 108
We find that this is true, so our answer is correct.

Answer:
The answer is
<h2>12</h2>
Step-by-step explanation:
The above variation is written as
where k is the constant of variation
when y = 9
x = 4
We have
k = yx²
k = 9(4)²
k = 9 × 16
k = 144
So the formula for the variation is
when y = 1
Cross multiply
x² = 144
Find the square root of both sides
x = √144
x = 12
Hope this helps you.
