Question

Paulina has completed 24 of the 42 math problems she was assigned for homework. She plans to finish her homework by completing 9 math problems each hour h. Write an equation to find the number of hours it will take Paulina to complete her math homework assignment.

Answer 1

2 hours to solve the 18 remaining problems

Explanation:

Paulina has (42-24) or 18 math problems remaining. Her rate of solving math problems is (9 problems/1 hr).

(18 math problems)/(9 problems/1 hr) = 2 hours to solve the 18 remaining problems.

Answer 2

To find the number of hours it will take Paulina to complete her math homework assignment, we can use the equation:

24 + 9h = 42

Where h represents the number of hours.
