Algebraic Expressions
Question 5 of 10

Which algebraic expression represents this word description?

"The product of two and the difference between a number and eleven."

A. [tex]11 - 2x[/tex]
B. [tex]2x - 11[/tex]
C. [tex]2(11 - x)[/tex]
D. [tex]2(x - 11)[/tex]



Answer :

To solve the question, let's break down the word description step-by-step:

### Step-by-Step Solution:

1. Identify the main operation:

The phrase "The product of" indicates that multiplication is involved.

2. Separate the components involved in the multiplication:

The description specifies two components to multiply:
- The number "two"
- The "difference between a number and eleven"

3. Understand the "difference between a number and eleven":

Let's represent "a number" with the variable [tex]\( x \)[/tex]. The difference between [tex]\( x \)[/tex] and 11 is expressed as:
[tex]\[ x - 11 \][/tex]

4. Combine the components using multiplication:

Now, multiply "two" by the difference we found:
[tex]\[ 2 \cdot (x - 11) \][/tex]

### Conclusion:

When we convert the given word description into an algebraic expression, it translates to:
[tex]\[ 2(x - 11) \][/tex]

### Verification with Given Options:

- Option A: [tex]\( 11 - 2x \)[/tex] does not match the description, because it subtracts twice the number from 11.
- Option B: [tex]\( 2x - 11 \)[/tex] does not match the description, because it subtracts 11 from twice the number.
- Option C: [tex]\( 2(11 - x) \)[/tex] does not match the description, because it multiplies twice the difference of 11 and the number.
- Option D: [tex]\( 2(x - 11) \)[/tex] correctly matches the description as it multiplies two by the difference between the number and eleven.

Thus, the correct algebraic expression is [tex]\( 2(x - 11) \)[/tex], which corresponds to:

Option D: [tex]\( 2(x - 11) \)[/tex]
