Question

Explain how to write and evaluate an algebraic expression that represents the situation.

Adi studied for three more hours.

 

Evaluate when h = 8.

 

Give a lot of information.

Answer 1

3 more hours than h is h+3. When h=8, this expression evaluates as 11 hours.

Answer 2

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.
