0.82644628099
Step-by-step explanation:
- - Let's solve for C.
Starting off with our equation:

Transform:

Solve for that:

Solve for that for the last time and your answer is
83-13 = 70
70/2 = 35
Thomas’s mileage is 35 miles
7n + 3 = 3n + 27
7n -3n =27-3
4n =24
n= 6.
Answer: Choice C) y = 30/x
Inverse variation equations are of the form y = k/x. In this case, k = 30. We can rearrange the format to get x*y = k after multiplying both sides by x. So y = 30/x can be turned into x*y = 30.
