Question 1: Identify the term, coefficient, variable, and constant in the expression 7x + 5.

Answer: {"term":"7x","constant":"5","variable":"x","coefficient":"7"}

Question 2: Write the algebraic expression with a term of 3y, a coefficient of 3, a variable y, and a constant 4.

Answer: 3y + 4

Question 3: In the expression 2a - 9, which part is the constant?

Answer: 9

Question 4: Simplify the expression: 5x + 2x - 3.

Answer: 7x - 3

Question 5: Construct an algebraic expression that has a term with coefficient 6, variable z, and a constant 8.

Answer: 6z + 8

Question 6: Identify the coefficient and term in the expression 4m + 7.

Answer: {"term":"4m","coefficient":"4"}

Question 7: A student writes the expression 'x + 3' and labels 'x' as the constant. Is this correct? Explain why or why not.

Answer: No. 'x' is a variable, not a constant.

Question 8: If the expression 9y - 4 has a term, a coefficient, a variable, and a constant, identify each.

Answer: {"term":"9y","constant":"-4","variable":"y","coefficient":"9"}

Question 9: Calculate and simplify: 3(2x + 4) - 5x.

Answer: 6x + 12 - 5x = x + 12

Question 10: Explain the difference between the term '6z' and the constant 6.

Answer: The term '6z' includes a variable with coefficient 6, while 6 is a constant number without variables.

Question 11: Identify the error: In the expression 2x + 3, a student labels 3 as a term. Is this correct? Why or why not?

Answer: No, 3 is a constant, not a term with variables. Terms are parts of an expression that can be separated by addition or subtraction.

Question 12: Using the expression 5a - 2, identify the term, coefficient, variable, and constant.

Answer: {"term":"5a","constant":"-2","variable":"a","coefficient":"5"}
