Sample Response: The variable is the number of hours Adi studied, the operation is addition, and the constant is 3. You can write the expression as h + 3 or 3 + h. To evaluate, substitute 8 in for the variable, h, and simplify. 8 plus 3 is 11. So Adi studied for 11 hours. Check any that you included in your response.The variable is the number of hours Adi studied, the operation is addition, and the constant is 3. You can write the expression as h + 3 or 3 + h.

Answer
A
The variable is the number of hours Adi studied, the operation is addition, and the constant is 3.
B
You can write the expression as h + 3 or 3 + h.
C
To evaluate, substitute 8 in for the variable, h, and simplify.
D
8 plus 3 is 11. So Adi studied for 11 hours.
Explanation
The sample response includes all four statements. It identifies the variable, operation, and constant; gives both equivalent expressions, h + 3 and 3 + h; explains substituting 8 for h; and concludes that 8 + 3 = 11, so Adi studied 11 hours.
