Final answer:
The algebraic expression with a term that has a coefficient of 3 is D. 3y + 1. The coefficient is the numerical part of a term with a variable, and in this case, the number 3 is the coefficient for the term 3y. Option D
Step-by-step explanation:
The question asks which algebraic expression contains a term with a coefficient of 3. A coefficient is the numerical factor of a term that contains a variable. By examining each expression, we can identify which one has the required coefficient.
A. 5y - 7: The coefficient of y is 5, not 3.
B. -2y + 5 + 3: The term + 3 does not contain a variable, so it is a constant, not a coefficient.
C. 3(9 - 6): This is a multiplication expression, not a term with a variable.
D. 3y + 1: The coefficient of y is 3, which is what we are looking for.
Therefore, option D is the correct answer.
