Question

which of the following expressions has a coefficient of 10 and a constant of 5? 10 + 5, 10 - 5, 10x + 5, 10 + 5x

Explanation:

Step1: Define coefficient/constant

A coefficient is the number multiplied by a variable; a constant is a fixed number with no variable.

Step2: Analyze each option

• $10+5$: No variable, so no coefficient.
• $10-5$: No variable, so no coefficient.
• $10x+5$: Coefficient of $x$ is $10$, constant is $5$.
• $10+5x$: Coefficient of $x$ is $5$, constant is $10$.

Answer:

$10x + 5$
