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

### Instruction:
John is 15 cm taller than Lena and 6 cm shorter than Rebeca. If John has a height of 152 cm, what is the height of Lena and Rebeca together?

### Response:
 Lena ana urefu wa cm 152 - cm 15 = <<152-15=137>>137.
Rebeca ana urefu wa cm 152 + cm 6 = <<152+6=158>>158.
Hivyo, Lena na Rebeca wangekuwa na urefu wa cm 137 + cm 158 = <<137+158=295>>295 wakiwa pamoja.
