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 
.
We are also told that Toby's office had already recycled 7 kilograms. So total kilogram of paper recycled in w weeks would be 
.
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:
Therefore, it will take 32 weeks for Toby's office to recycle a total of 39 kilograms of paper.

Combine like terms.
(-3+6)×(-9)
Simplify.
(3)×(-9)
Simplify. Remember, a negative times a positive is ALWAYS a negative.

There are four banana, one strawberry and one water-melon smoothies, six in all.
Assuming all smoothies are identical when we pick, then the probability of picking a particular one is one divided by the total number (of smoothies).
Since there are four banana smoothies, the probability of picking a banana smoothie is four divided by six, or four-over-six, or two-thirds.
There are now five smoothies remaining, of which three are banana. Therefore the probability of picking another banana is three-over-five, or three fifths.
The final probability is the product of the individual (we call it a two-step experiment), or two-third multiplied by three-fifths, equal to two-fifths, or forty percent.
Recall that if the first banana smoothie had been put back in the batch, the probability would come out different.
