Runners race around a rectangular park during the city marathon. The length of the park is 6 miles. The width of the park is 7 miles. Which is the correct unit of measurement to use when figuring out how many miles someone would run during the marathon? A. miles3 B. miles C. miles2
Answers
The question asks us to the miles someone would run during the marathon. Since, the marathon goes around the park, the question is asking for the perimeter of the rectangular park. The perimeter for a rectangle is:
P=2(l+w)
P=2l+2w
The ending unit of measurement would be miles.
P=2(6+7)
P=2(13)
P=26 miles

The ticket for an adult costs $10 and the ticket for a child costs $7
- Let adults tickets be a
- Let children tickets be c
Based on the information given, the equation to solve the question will be:
2a + 4c = 48
5a + 2c = 64
Multiply equation i by 5
Multiply equation ii by 2
10a + 20c = 240
10a + 4c = 128
Subtract the equations
16c = 112
c = 112/16
c = 7
The ticket for a child is $7
Since 2a + 4c = 48
2a + 4(7) = 48
2a + 28 = 48
2a = 48 - 28
2a = 20
a = 20/2
a = 10

Answer:
The price for one adult is $10 while the price for one child is $7
Step-by-step explanation:
Let
price for an adult = a
price for a child = b
2a + 4b = 48.............(i)
5a + 2b = 64.............(ii)
make a subject of the formula in equation (i)
2a = 48 - 4b
divide through by 2
a = 24 - 2b
Insert the value of a in equation (ii)
5(24 - 2b) + 2b = 64
120 - 10b + 2b = 64
collect like terms
- 8b = 64 - 120
-8b = -56
divide both sides by -8
b = 7
insert the value of b in equation(i)
2a + 4(7) = 48
2a + 28 = 48
2a = 48 - 28
2a = 20
divide both sides by 2
a = 10
The price for one adult is $10 while the price for one child is $7

What are ratio and proportion?
A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Given, Last year the girls’ basketball team had 8 fifth-grade students and 7 sixth-grade students which is 8/7.
