Answer:
Cost of child movie = x = $8
Cost of adult movie = y = $10.25
Step-by-step explanation:
Let cost of child movie = x
Cost of adult movie = y
Now converting statements into mathematical expressions:
Hansen family bought 2 child and 2 adult movie tickets and paid $36.50.
Owens family bought 5 child and 2 adult tickets and paid $60.50.
Let:
Subtract both equations:
So, we get Value of x =8
Now, putting value of x in eq(1) to find value of y
So, we get Value of y = 10.25
So,
Cost of child movie = x = $8
Cost of adult movie = y = $10.25

Step-by-step explanation:
The time that will be taken for Daniel to swim to the boat ramp will be 3.34 minutes.
<h3>How to calculate time taken</h3>
Let the distance be x.
Based on the information given, the calculation will be:
Sin 53° = 400/x
0.7986 = 400/x
x = 500 feet
Time = Distance / Speed
Time = 500/150 = 3.33 minutes.
The distance of the boat ramp from the campsite will be:
Cos53° = y/500
0.60 = y/500
y = 300 feet.
Distance will be:
= 1600 - 300 = 1300 feet
The minutes that it takes him to jog from the boat ramp to the campsite will be:
Distance = 1300 feet
Rate = 4 miles per hour = 352 feet per minutes
Time = Distance / Rate
Time = 1300/352 = 3.69 minutes
The total time taken will be:
= 3.33 + 3.69
= 7.02 minutes

Answer:
-2 4/7
Step-by-step explanation:
−3 2/7 − (−5/7)
Subtracting a negative is like adding
−3 2/7 + (5/7)
Since the signs are difference we subtract and take the sign of the larger number
3 2/7 - 5/7
Borrow from the whole number
2+ 7/7 + 2/7 - 5/7
2 9/7 - 5/7
2 4/7
The sign of the larger number is negative so add the negative sign
- 2 4/7
