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

### Instruction:
 Louise anaweka picha 30 kwenye ukuta. Anaweka baadhi yao wima, nusu yao kwa usawa, kisha anaweka picha 5 zilizobaki kwa bahati mbaya. Louise aliweka picha ngapi wima?


### Response:
 Kuna picha 30 * 0.5 = <<30*0.5=15>>15 zinazowekwa kwa usawa.
Hivyo jumla ya picha zinazowekwa kwa usawa au kwa bahati mbaya ni 15 + 5 = <<15+5=20>>20.
Hivyo, kuna picha 30 - 20 = <<30-20=10>>10 zinazowekwa wima.
