The cost per adult ticket is $13 and the cost per children ticket is $8
Step-by-step explanation:
Let the cost of adult tickets be 'x'
Let the cost of children tickets be 'y'
2x + 3y = 50
2x = 50 - 3y
x = (50 - 3y) /2
3x + 4y = 71
[3(50-3y) /2 ]+ 4y = 71
(150 - 9y) /2 + 4y = 71
150 - 9y + 8y = 142
150 - y = 142
y = 150 - 142
y = 8
x = (50-3y) /2
x = (50-24) /2
x = 13
The cost per adult ticket is $13 and the cost per children ticket is $8
Answer:
First, you need to add 15x to both sides in order to get y by itself. Then, you need to divide all the numbers by 12. Your answer should be Y=1.25x+7. I hope this helps!

Answer:
The Range of possible measures for the third side is; 2 < C < 16
Step-by-step explanation:
In a triangle with sides A , B and C , the sum of the length of any two sides of a triangle must be greater than the third side:
Given the two sides of a triangle are 7 and 9.
Let A = 7 and B = 9 then;
B-A< C < A+B
Then; the range of C can be:
9-7 < C < 7+9
Simplify:
2 < C < 16
Therefore, the range of possible measures for the third side is; 2 < C < 16
The domain of the relation is 7,13 and the range of the relation is 4,20. I hope this helps.
