Answer:

Step-by-step explanation:   When representing Mario’s age as “a,” we can use the expression “a + 5” to represent his brother’s age, as he is 5 years older than Mario. This simple algebraic representation allows us to easily calculate the brother’s age based on Mario’s age.

In this scenario, using algebraic expressions helps us understand the relationship between Mario’s age and his brother’s age. By defining Mario’s age as “a” and applying the given information that his brother is 5 years older, we can express the brother’s age as “a + 5.”

This approach provides a clear and concise way to solve for Mario’s brother’s age based on the given information about their age difference.

Therefore, the age of Mario’s brother is a + 5.
