To determine the number of miles Kyle ran based on the information given, we know:
Cameron ran 5 miles less than Kyle. If we let \( x \) represent the number of miles Kyle ran, we can express this relationship with the equation:
\[ x - 5 = 9 \]
This means that if you add 5 miles to Cameron's total (9 miles), you will arrive at the total miles Kyle ran. Rearranging gives:
\[ x = 9 + 5 \]
\[ x = 14 \]
So, the correct equation that represents how many miles Kyle ran is:
**B: \( x - 5 = 9 \)**
