--> 290 = 5/9*(K - 32) --> 290 x5/9 = K-32 --> 522 = k-32 --> k = 554
Ans D ....its very simple..hope u understand..

Well you got it wrong =) Not "290 x5/9" but "290/(5/9)"
I see what I did wrong here. I got K-32=522 instead of K=522+32 I did K=522-32. As always just need to pay attention to details.
Thanks,
TheGuest

We start by substituting 290 for T and we obtain:TheGuest wrote:If T=5/9*(K - 32), and if T=290, then K=
(A) 1,738/9
(B) 322
(C) 490
(D) 554
(E) 2,898/5
290 = 5/9(K - 32)
To eliminate the fraction, we multiply the entire equation by 9 and we have:
290 x 9 = 5(K - 32)
We next divide both sides by 5 and then solve for K:
58 x 9 = K - 32
522 = K - 32
554 = K
Answer: D
