Understanding the Problem

In this article, we will explore three different descriptions and their corresponding expressions. We will analyze each description and determine which one is paired with its correct expression. This will involve breaking down each description, identifying the key elements, and then matching them with the correct expression.

Description A: Four Less Than the Quotient of a Number Cubed and Seven, Increased by Three

Description A states that we need to find the expression that represents "Four less than the quotient of a number cubed and seven, increased by three." Let's break down this description and identify the key elements.

Four less than: This means we need to subtract 4 from the result.
Quotient of a number cubed and seven: This means we need to divide the cube of a number by 7.
Increased by three: This means we need to add 3 to the result.

Using these key elements, we can create an expression that represents this description. The expression would be:

4-\frac{n^3}{7}+3

This expression represents the description by first cubing the number (n^3), then dividing it by 7, subtracting 4, and finally adding 3.

Description B: Five Times the Difference of a Number Squared and Six

Description B states that we need to find the expression that represents "Five times the difference of a number squared and six." Let's break down this description and identify the key elements.

Five times: This means we need to multiply the result by 5.
Difference of a number squared and six: This means we need to subtract 6 from the square of the number.

Using these key elements, we can create an expression that represents this description. The expression would be:

5(6-n^2)

This expression represents the description by first squaring the number (n^2), then subtracting 6, and finally multiplying the result by 5.

Description C: Nine

Description C simply states "Nine." This description does not provide any information about how to manipulate a number, so we cannot create an expression that represents it.

Conclusion

In conclusion, we have analyzed three different descriptions and determined which one is paired with its correct expression. Description A is paired with the expression $4-\frac{n^3}{7}+3$ , while Description B is paired with the expression $5(6-n^2)$ . Description C does not have a correct expression because it does not provide any information about how to manipulate a number.

Key Takeaways

When analyzing a description, identify the key elements and break them down into smaller parts.

Final Thoughts

Q: What is the main difference between Description A and Description B?

A: The main difference between Description A and Description B is the order of operations. Description A involves cubing the number, dividing it by 7, subtracting 4, and then adding 3. Description B involves squaring the number, subtracting 6, and then multiplying the result by 5.

Q: How do I know which expression is correct for a given description?

A: To determine which expression is correct for a given description, you need to carefully read the description and identify the key elements. Then, use these key elements to create an expression that represents the description. Make sure to follow the order of operations when creating the expression.

Q: What is the significance of the order of operations in creating expressions?

A: The order of operations is crucial in creating expressions because it determines the order in which mathematical operations are performed. If the order of operations is not followed correctly, the expression may not represent the description accurately.

Q: Can I use the same expression for multiple descriptions?

A: No, you cannot use the same expression for multiple descriptions. Each description requires a unique expression that accurately represents the description. Using the same expression for multiple descriptions can lead to incorrect results.

Q: How do I avoid common mistakes when creating expressions?

A: To avoid common mistakes when creating expressions, make sure to:

Carefully read the description and identify the key elements.
