Question

The equation p = h + 3 shows how the length of Ted's essay depends on the number of hours he spends writing this week. The variable h represents the number of hours he spends writing this week, and the variable p represents the total number of pages that have been written. How many hours will Ted have to spend writing this week in order to have written a total of 9 pages?

a) 2 hours
b) 4 hours
c) 6 hours
d) 9 hours

Answer 1

Ted will have to spend 6 hours writing this week in order to have written a total of 9 pages.

Step-by-step explanation:

To find how many hours Ted will have to spend writing this week in order to have written a total of 9 pages, we need to solve the equation p = h + 3 for h. Since p represents the total number of pages and is given as 9, we have 9 = h + 3. To isolate h, we subtract 3 from both sides of the equation. 9 - 3 = h, which simplifies to h = 6 hours. Therefore, Ted will have to spend 6 hours writing this week.
