In this article, we will delve into a mathematical problem that involves understanding fractions and algebraic expressions. The problem revolves around Barry's baseball card collection and his brother's collection. We will explore how to represent the number of baseball cards Barry has in terms of the number of cards his brother has.

The Problem Statement

Barry has 17 more than two-thirds of the number of cards in his brother's baseball card collection. If $x$ represents the number of baseball cards his brother has, we need to find an expression that represents the number of baseball cards Barry has.

Breaking Down the Problem

To solve this problem, we need to understand the concept of fractions and how to represent them algebraically. We are given that Barry has 17 more than two-thirds of the number of cards in his brother's collection. This means that we need to find two-thirds of the number of cards his brother has and then add 17 to it.

Representing Two-Thirds Algebraically

Two-thirds of a number can be represented algebraically as $\frac{2}{3}x$ , where $x$ is the number of cards his brother has. This is because we are multiplying the number of cards by $\frac{2}{3}$ to find two-thirds of the number.

Adding 17 to the Expression

Now that we have found two-thirds of the number of cards his brother has, we need to add 17 to it. This can be represented algebraically as $\frac{2}{3}x + 17$ . This expression represents the number of baseball cards Barry has in terms of the number of cards his brother has.

The Final Expression

Therefore, the expression that represents the number of baseball cards Barry has is $\frac{2}{3}x + 17$ .

Conclusion

In this article, we have explored a mathematical problem that involves understanding fractions and algebraic expressions. We have seen how to represent two-thirds of a number algebraically and how to add 17 to the expression to find the number of baseball cards Barry has. The final expression is $\frac{2}{3}x + 17$ , which represents the number of baseball cards Barry has in terms of the number of cards his brother has.

Key Takeaways

Two-thirds of a number can be represented algebraically as $\frac{2}{3}x$ .
Adding 17 to the expression $\frac{2}{3}x$ gives us the number of baseball cards Barry has.
The final expression that represents the number of baseball cards Barry has is $\frac{2}{3}x + 17$ .
