If the cost of adult ticket is x and that of children ticket is y
Then 3x +y = $38
3x+2y =$52, solving simultaneously
we subtract the two equation,
-y = -14
thus; y =14
to get x we substitute y with 14
3x = 38-14
3x =24
x =8
Therefore, the cost of 1 adult ticket is $8 while the cost of children ticket is $14

Answer:
20 sides
We know that if we find the size of an exterior angle for the given regular polygon whose exterior angle is 18∘, we can find the number of sides. Where, n is the number of sides. Therefore, there are 20 sides in the given regular polygon whose exterior angle is 168∘.
Answer:
1.2 minutes
Step-by-step explanation:
The applicable relationship between speed, distance, and time is ...
time = distance/speed
= (3 km)/(150 km/h) = (3/150) h = 1/50 h
= (60 min)/50 = 1.2 minutes
