Answer:
x + y = 13
98x + 115y = z
Step-by-step explanation:
Let x represent the time spent taking class in Westside community college
Let y represent the time spent taking class in Pinewood community college
Let z represent the combined total amount paid for the class fees.
The total combined time for the two school is given as:
x + y = 13.
For the combined total amount; we multiply the price for each school with the time spent on the school and sum them together.
Westside: 
Pinewood: 
The combined total amount represented as z is given as:
z = 98x + 115y

Step-by-step explanation:
The total length of the border = 50.2 yards
Step-by-step explanation:
Step 1 :
Given,
Diameter of the circular region = 16 yards
We need to compute the total length of the border.
Step 2 :
The total length of the border can be obtained by computing circumference of the region with the given diameter
Circumference = 2(pi)(r)
where r is the radius
here diameter = 16, so radius = 8 yards
Hence circumference = 2 (3.14) 8 = 50.24 yards
Step 3 :
Answer :
The total length of given border = 50.2 yards (rounded off to nearest 10th)
