In mathematics, a number sentence is a statement that contains numbers and variables, and is used to represent a mathematical relationship or equation. When analyzing a number sentence, it's essential to understand the different components that make up the sentence. In this article, we will focus on identifying the underlined part of the number sentence $5x + 4 = 34$ .

What is a Number Sentence?

A number sentence is a mathematical statement that contains numbers, variables, and mathematical operations. It is used to represent a mathematical relationship or equation, and can be used to solve for unknown values. Number sentences can be simple or complex, and can involve various mathematical operations such as addition, subtraction, multiplication, and division.

Components of a Number Sentence

A number sentence typically consists of several components, including:

Variables: These are letters or symbols that represent unknown values. In the number sentence $5x + 4 = 34$ , the variable is $x$ .
Constants: These are numbers that do not change value. In the number sentence $5x + 4 = 34$ , the constants are $5$ and $4$ .
Coefficients: These are numbers that are multiplied by a variable. In the number sentence $5x + 4 = 34$ , the coefficient is $5$ .
Terms: These are the individual parts of a number sentence that are separated by addition or subtraction signs. In the number sentence $5x + 4 = 34$ , the terms are $5x$ and $4$ .
Equation: This is a number sentence that states that two expressions are equal. In the number sentence $5x + 4 = 34$ , the equation is $5x + 4 = 34$ .

Identifying the Underlined Part

Now that we have discussed the components of a number sentence, let's focus on identifying the underlined part of the number sentence $5x + 4 = 34$ . The underlined part is $5x$ .

What is the Underlined Part?

The underlined part, $5x$ , is a term. A term is a single part of a number sentence that is separated by addition or subtraction signs. In this case, the term $5x$ is a product of a coefficient ( $5$ ) and a variable ( $x$ ).

Why is it a Term?

The underlined part, $5x$ , is a term because it meets the following criteria:

It is a single part of the number sentence.
It is separated from the other part of the number sentence by an addition sign.
It is a product of a coefficient ( $5$ ) and a variable ( $x$ ).

Conclusion

In conclusion, the underlined part of the number sentence $5x + 4 = 34$ is a term. A term is a single part of a number sentence that is separated by addition or subtraction signs, and is a product of a coefficient and a variable. Understanding the components of a number sentence is essential for analyzing and solving mathematical problems.

Q: What is a term in a number sentence?

A: A term is a single part of a number sentence that is separated by addition or subtraction signs, and is a product of a coefficient and a variable.

Q: How do I identify the underlined part of a number sentence?

A: To identify the underlined part of a number sentence, look for the part that is separated by addition or subtraction signs. If it is a product of a coefficient and a variable, it is a term.

Q: What is the difference between a coefficient and a constant?

A: A coefficient is a number that is multiplied by a variable, while a constant is a number that does not change value.

Q: Can a number sentence have more than one variable?

A: Yes, a number sentence can have more than one variable. For example, the number sentence $2x + 3y = 5$ has two variables, $x$ and $y$ .

Q: Can a number sentence have more than one equation?

A: No, a number sentence can only have one equation. However, it can have multiple terms and variables.

Q: How do I solve a number sentence?

A: To solve a number sentence, you need to isolate the variable by performing inverse operations. For example, to solve the number sentence $2x + 3 = 5$ , you would subtract 3 from both sides and then divide both sides by 2.

Q: What is the importance of understanding number sentences?

A: Understanding number sentences is essential for analyzing and solving mathematical problems. It helps you to identify the components of a number sentence, solve for unknown values, and represent mathematical relationships or equations.
