let the number of adult tickets be x and the number of children tickets be y
3x + y = 164...equ(1)
2x + 3y = 174....equ(2)
multiplying equation 1 by 3
9x + 3y = 492
subtracting equation 2 from 1
7x = 318
x = 45.43 dollars
substituting the value of x into the equation
3(45.428) + y = 164
y = 164 - 3(45.428)
∴y = 27.71 dollars

Step-by-step explanation:
Based on the coordinates of triangle RST, we can infer that triangle RST is <u>not a right-angled triangle. </u>
<h3>Is triangle RST a right-angled triangle?</h3>
For this to be a right-angled triangle, the Pythagoras theorem has to apply where:
Largest side² = Side A² + Side B²
Lengths of the triangle:
RS² = (4 - 2)² + (4 - 3)²
= 5
ST² = (5 - 4)² + (0 - 9)²
= 17
TR² = (2 - 5)² + (3 - 0)²
= 18
We can see that:
18 ≠ 17 + 5
This is therefore not a right-angled triangle.
