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

### Instruction:
Luther designs clothes for a high fashion company. His latest line of clothing uses both silk and cashmere fabrics. There are ten pieces made with silk and half that number made with cashmere. If his latest line has thirteen pieces, how many pieces use a blend of cashmere and silk?

### Response:
 Luther ana vipande 10 / 2 = <<10/2=5>>5 vilivyotengenezwa kwa pamba ya kashmiri.
Ana vipande 13 - 10 = <<13-10=3>>3 vilivyotengenezwa bila hariri kwa kutumia pamba ya kashmiri pekee.
Hivyo, Luther ana vipande 5 - 3 = <<5-3=2>>2 vilivyotengenezwa kwa kutumia mchanganyiko wa pamba ya kashmiri na hariri.
