By Cramer's rule, the solution can be found as the ratio of determinants. The numerator is the matrix with the right-side constants replacing the coefficients of the variable of interest. The denominator is the matrix of coefficients.
The solution is ...

Answer:
285 mi
Step-by-step explanation:
We can see that for every gallon, Josh drives 30 more miles. This means that he will drive 30*9.5 mi.
30*9.5 = 285
Steve is 1.2 times faster than Paul.
<h3>
What is a ratio?</h3>
The quantitative relationship between two values indicating how frequently one value is contained within the other.
For example: Speed = Distance / Time
Total distance covered by both Steve and Paul = 100m
Total time taken by Steve = 10s
Steve's speed = 100 / 10 = 10m/s
Total time taken by Paul = 12s
Paul's speed = 100 / 12 = 8.33m/s
Ratio of Steve's speed to Paul's speed = 10 / 8.33 = 1.2
Hence we can say that Steve is 1.2 times faster than Paul.
