Combine like terms: 0.5x + 1.5x.

Combine like terms: 0.5x + 1.5x.

• A. 1x
• B. 3x
• C. 2x
• D. 0x

Answer: (C)

To combine like terms in the expression 0.5x + 1.5x, you're adding coefficients of the same variable, which is x in this case. The coefficients are 0.5 and 1.5. When you add these coefficients together: 0.5 + 1.5 = 2. Since both terms share the variable x, you simply attach the result to the variable, resulting in 2x. This illustrates the principle of combining like terms, where terms that share the same variable can be simplified by adding their coefficients together. Thus, the correct answer is 2x.
