Answer:

5 yr and 39 yr

Step-by-step explanation:

Let x = the age of the younger

then 7x + 4 = the age of the older

Now x + 7x + 4 = 44

8x + 4 = 44

8x = 40

x = 5

7x + 4 = 7(5) + 4 =  35 + 4 = 39

Check:  5 + 39 = 44

iren [92.7K]

Answer:

32 weeks.

Step-by-step explanation:

Let w represent number of weeks.

We have been given that the new plan will have the office recycling 1 kilogram of paper each week. So kilograms of paper recycled in w weeks would be 1\cdot w=w.

We are also told that Toby's office had already recycled 7 kilograms. So total kilogram of paper recycled in w weeks would be w+7.

Since Toby's office has to recycle a total of 39 kilograms of paper, so we will equate 39 with paper recycled in w weeks as:

w+7=39

w+7-7=39-7

w=32

Therefore, it will take 32 weeks for Toby's office to recycle a total of 39 kilograms of paper.
