Answer:
6 m
Step-by-step explanation:

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:
B. x < 6 and x > -28
Step-by-step explanation:
|x + 11| < 17
-17 < x + 11 < 17
Subtract 11 from all 3 sides.
-28 < x < 6
x > -28 and x < 6
