Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
When Nathan is cold, he adds an extra blanket to his bed. Each blanket warms him up by 3 degrees. One night, he was cold enough that he added half of the 14 blankets in his closet on his bed. How many degrees did the blankets warm Nathan up?

### Response:
 Nathan aliweka nusu ya blanketi 14, hivyo aliweka blanketi 14/2 = <<14/2=7>>7.
Kila blanketi ilimwongezea joto kwa digrii 3, hivyo blanketi 7 zilimwongezea joto kwa digrii 7 * 3 = <<7*3=21>>21.
