2 answers:
Answer: C
Step-by-step explanation:
The pythagorean theorem states that all right triangle side lengths can go into the equation +
=
All you need to do is insert the given number and see if it turns out true.
If you go through each equation, C is the only one that turns out wrong, making it not possible.
(<em>For example, for A, (5×5) + (12×12) = 13×13. This becomes 169 = 169, which of course is true.)</em>

Answer:
Children ticket cost $30 and adult ticket costs $40.
Step-by-step explanation:
Given that:
x = price of a child ticket
y = price of an adult ticket
According to given statement;
3x+2y=170 Eqn 1
4x+6y=360 Eqn 2
Multiplying Eqn 1 by 3
3(3x+2y=170)
9x+6y=510 Eqn 3
Subtracting Eqn 2 from Eqn 3
(9x+6y)-(4x+6y)=510-360
9x+6y-4x-6y=150
5x=150
Dividing both sides by 5
Putting x=30 in Eqn 1
3(30)+2y=170
90+2y=170
2y = 170-90
2y = 80
Dividing both sides by 2
Hence,
Children ticket cost $30 and adult ticket costs $40.
