A system of equations is good for a problem like this.
Let x be the number of student tickets sold
Let y be the number of adult tickets sold
x + y = 200
2x + 3y = 490
x = 200 - y
2(200 - y) + 3y = 490
400 - 2y + 3y = 490
400 + y = 490
y = 90
The number of adult tickets sold was 90.
x + 90 = 200 --> x = 110
2x + 3(90) = 490 --> 2x + 270 = 490 --> 2x = 220 --> x = 110
The number student tickets sold was 110.

Answer:
it don't make sense that there isn't a question...
Step-by-step explanation:
To find the missing length of a triangle we will use the Pythagorean Theorem.
Pythagoream Theorem = a^2 + b^2 = c^2
With this formula, we can find the missing side as follows:
27^2 + 36^2 = c^2
729 + 1,296 = C
2,025 = C
45 = C^2
There for we can conclude that the answer for the missing side is: 45 inches.
