Understanding the Problem

When dealing with algebraic expressions, it's essential to understand the mathematical operations involved in the given phrase. In this case, we're asked to find the expression that represents "three times the product of p and q." To solve this problem, we need to break down the phrase into its individual components and translate them into mathematical notation.

Breaking Down the Phrase

The phrase "three times the product of p and q" can be broken down into two main components:

  1. Product of p and q: This means we need to multiply p and q together. In mathematical notation, this is represented by pq.
  2. Three times: This means we need to multiply the product of p and q by 3. In mathematical notation, this is represented by 3 * pq.

Translating the Phrase into Algebraic Notation

Now that we've broken down the phrase into its individual components, we can translate it into algebraic notation. The product of p and q is represented by pq, and three times this product is represented by 3 * pq.

Evaluating the Answer Choices

Let's evaluate the answer choices to see which one represents the phrase "three times the product of p and q":

A) pq: This option only represents the product of p and q, but not three times this product.

B) 3pq: This option represents three times the product of p and q, which matches our translation of the phrase.

C) 3 + pq: This option represents the sum of 3 and the product of p and q, but not three times this product.

D) pq/3: This option represents the quotient of the product of p and q divided by 3, but not three times this product.

Conclusion

Based on our analysis, the correct answer is B) 3pq, which represents three times the product of p and q.

Additional Examples

To further illustrate the concept, let's consider a few more examples:

  • "Two times the sum of p and q" can be represented by 2(p + q).
  • "Four times the difference of p and q" can be represented by 4(p - q).
  • "Five times the quotient of p and q" can be represented by 5(p/q).

Q&A: Algebraic Expression Translation

Q: What is the difference between an algebraic expression and an equation?

A: An algebraic expression is a mathematical expression that contains variables, constants, and mathematical operations, but does not contain an equal sign (=). An equation, on the other hand, is a mathematical statement that contains an equal sign (=) and is used to solve for a variable.

Q: How do I translate a phrase into an algebraic expression?

A: To translate a phrase into an algebraic expression, follow these steps:

  1. Break down the phrase into its individual components.
  2. Identify the mathematical operations involved (e.g., multiplication, addition, subtraction).
  3. Represent each component using algebraic notation.
  4. Combine the components using the correct mathematical operations.

Q: What is the order of operations in algebraic expressions?

A: The order of operations in algebraic expressions is:

  1. Parentheses: Evaluate expressions inside parentheses first.
  2. Exponents: Evaluate any exponential expressions next.
  3. Multiplication and Division: Evaluate any multiplication and division operations from left to right.
  4. Addition and Subtraction: Finally, evaluate any addition and subtraction operations from left to right.

Q: How do I simplify an algebraic expression?

A: To simplify an algebraic expression, follow these steps:

  1. Combine like terms: Combine any terms that have the same variable and coefficient.
  2. Eliminate any unnecessary parentheses: Remove any unnecessary parentheses to make the expression easier to read.
  3. Rewrite the expression in a simpler form: Use the distributive property to rewrite the expression in a simpler form.

Q: What is the distributive property in algebra?

A: The distributive property is a mathematical property that allows us to multiply a single term by multiple terms inside parentheses. It is represented by the formula:

a(b + c) = ab + ac

Q: How do I evaluate an algebraic expression?

A: To evaluate an algebraic expression, follow these steps:

  1. Substitute the given values for any variables.
  2. Simplify the expression using the order of operations.
  3. Evaluate any remaining mathematical operations.

Q: What is the difference between a variable and a constant in algebra?

A: A variable is a letter or symbol that represents a value that can change. A constant, on the other hand, is a value that does not change.

Q: How do I solve an algebraic equation?

A: To solve an algebraic equation, follow these steps:

  1. Isolate the variable: Use inverse operations to isolate the variable on one side of the equation.
  2. Simplify the equation: Simplify the equation by combining like terms.
  3. Solve for the variable: Use the inverse operation to solve for the variable.

Q: What is the difference between a linear equation and a quadratic equation?

A: A linear equation is an equation in which the highest power of the variable is 1. A quadratic equation, on the other hand, is an equation in which the highest power of the variable is 2.

Q: How do I graph an algebraic expression?

A: To graph an algebraic expression, follow these steps:

  1. Identify the type of function: Determine whether the expression represents a linear, quadratic, or other type of function.
  2. Find the x-intercepts: Find the values of x that make the expression equal to zero.
  3. Find the y-intercept: Find the value of y when x is equal to zero.
  4. Plot the graph: Use the x-intercepts and y-intercept to plot the graph of the expression.

Q: What is the difference between a function and a relation in algebra?

A: A function is a relation in which each input value corresponds to exactly one output value. A relation, on the other hand, is a set of ordered pairs that do not necessarily have a one-to-one correspondence between input and output values.
