Equation:
Answer: xx =

Answer 1

To determine the average number of miles Brandon needs to ride each day over the next 5 days to reach his goal of 21 miles, we can set up the equation based on the information provided.

1. Total miles Brandon wants to ride: 21 miles
2. Miles already ridden: 6 miles
3. Miles left to ride: \( 21 - 6 = 15 \) miles
4. Number of days left to ride: 5 days

Let \( x \) be the average number of miles he needs to ride each day for the next 5 days. The total miles he needs to ride in the next 5 days is 15 miles, so we can set up the equation as follows:

\[ 5x = 15 \]

Now, solve for \( x \):

\[ x = \frac{15}{5} = 3 \]

So, Brandon needs to ride an average of 3 miles each day.

Final Answer:

Equation: \( 5x = 15 \)

Answer: \( x = 3 \)
