290=\frac{5}{9}(K32) 58*9=k31 i rounded 9 to 10 so 58058+31=k then i choose d, no point in doing calculations to waste time

\(290 = \frac{5}{9} * (k32)\) \(k = 290*\frac{9}{5} + 32\) k = 58*9 + 32 Answer would be ending with 4; only option D = 554 fits in Answer = D

Can someone please explain the algebra that the previous poster used. How did they jump from the 1st equation to the 2nd?

Sure, look below: Given: T = 5/9 * (K  32) > Multiply both sides by 9/5, we get > 9/5T = (5/9 * 9/5) * (K32) > 9/5 * T = 1 * (K32) > (9/5 )T = K 32 (as x*1 = x) > Now add 32 to both sides (to transfer 32 from K32 towards T), we get > (9/5)T + 32 = K Now susbtitute T = 290 in the last equation, we get (9/5) * 290 + 32 = K > K = 9 *58 + 32 = 522 + 32 = 544.

Ah they multiplied by the reciprocal, I misunderstood that.

Just want to remind everyone to use estimation for problems such as this one. You will multiply 290 by something slightly less than 2 and then add 32. We know it is a whole number and greater than 500, only D is that...

Very good point. What's your strategy upon seeing a question such as that and deciding which tactic to use?

Honestly, it is something that you should be looking at most of the time. This is a thinking exam, not at math exam.

True, but if you do attempt to answer a question without doing math then there's a higher risk of getting muddled or making careless errors. There's obviously a balancing act and it'd be preferable to have some sort of guidelines to apply in choosing how to tackle a problem

(A) 1,738/9 (B) 322 (C) 490 (D) 554 (E) 2,898/5 We start by substituting 290 for T and we obtain: 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 The answer is D.

i tried to do this way and got the answer wrong.please tell me where did I go wrong.
290 * 9 = 5k  160 k = 2610/5 k = 522

Answer: D. hi Bunuel, i used arithmetic method to solve it, but it took long time. can you explain based on which rule you you divided both parts by 5/9 ? i revied all kinds of agebra articles but still encounter such simple gaps
