Answer:
There were 150 student tickets and 200 adult tickets sold
Step-by-step explanation:
Let s and a represent the numbers of student and adult tickets sold, respectively. Then the two equations are ...
s + a = 350 . . . . . . total number of tickets sold
12.50s + 16.00a = 5075 . . . . . .total value of tickets sold
___
<u>Solution</u>
The first equation lets us write an expression for s:
s = 350 - a
We can substitute this into the second equation:
12.50(350 -a) +16.00a = 5075
3.50a + 4375 = 5075 . . . . . . . . . simplify
3.50a = 700 . . . . . . . . . . . . . . . . . subtract 4375
a = 200 . . . . . . . . . . . . . . . . . . . . . divide by 3.50
There were 200 adult tickets and 150 student tickets sold.

Answer:
168
Step-by-step explanation:
area of base triangle = 6×4= 24÷2= 12
2 triangles= 12×2=24
9×5= 45 ×2=90
6×9 =54
54+90+24=168
O2 is the answer because without that
Answer:
y = 2
Step-by-step explanation:
y varies inversely with x setup is:
y = k/x
7 = (find 'k')
k = 7/1 · 2/3
k = 14/3
use what you know about 'k' and 'x' to solve for 'y'
y = 14/3 ÷ 7/3 (remember to multiply by the reciprocal when dividing fractions)
y = 14/3 · 3/7
y = 2
