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

### Instruction:
In her first term, Governor Sandoval gave twice as many commencement addresses as Governor Hawkins. Governor Sloan gave ten more commencement addresses than Governor Sandoval in the same amount of time. If Governor Sandoval gave 12 commencement addresses, how many commencement addresses did the three of them give altogether?

### Response:
 Kwa kuwa Gavana Sandoval alitoa hotuba za kuhitimu 12, mara mbili ya idadi ya hotuba alizotoa Gavana Hawkins, Gavana Hawkins alitoa hotuba za kuhitimu 12/2 = <<12/2=6>>6.
Wote wawili walitoa hotuba za kuhitimu 6+12 = <<6+12=18>>18 jumla.
Gavana Sloan alitoa hotuba za kuhitimu 10 zaidi ya Gavana Sandoval, jumla ya hotuba za kuhitimu 12+10 = <<12+10=22>>22.
Jumla, wote watatu walitoa hotuba za kuhitimu 22+18 = <<22+18=40>>40.
