<p>yeah, 12 is right...100%</p>
<p>jessy1027, the equation was x + (2x - 9) = 180.
Solve for x and you get 63, which is the right answer.</p>
<p>jessy -- trial and error, woot. i ended up with like 63.</p>
<p>@mj93: I got 9, but where were other possibilities, so long as it satisfied the 6a+3b+c=18 requirement (I used a=1, b=1, and c=9).</p>
<p>If you use a=1, b=2, and c=6, then 12 was indeed an answer.</p>
<p>the x sqrt root of 5 question killed me. what did you guys get for that? how?!</p>
<p>LOL</p>
<p>I've seen 6, 9, and 12 for that question. I got a value between 104 and 105 and rounded up. How strange. Still, I fail to see how it was wrong.</p>
<p>((6<em>1.8)/18)+((3</em>1.8)/18)+(1.8/18)=1</p>
<p>what is the answer for the question that asked for number of circles that can be made in 9pi which have center P . I thought it had more than four because diameter can be vary since there is no specification of numbers.(it did not state that it had to be integers.. so..) please,, what is the answer?</p>
<p>what else was in the experimental math besides the rst one?</p>
<p>ok... 1.8 is not right because it doesnt not fit to the original equation..
plug 1.8 to each one and it wont work</p>
<p>just find C.D. and solve it.</p>
<p>this is the easiest way to solve the abc problem:</p>
<p>you are given: a/3 + b/6 + c/18 = 1</p>
<p>notice that you are dividing 1 into 3 parts, so each can be 1/3.</p>
<p>set each term equal to 1/3, and get that a=1, b=2, c=6...and therefore abc = 12</p>
<p>wait did the problem specify there cant be same integers?
I put a=1 b=1 c=9 therefore 9 o ****</p>

<p>***, each term does NOT have to be 1/3 to = 1</p>
<p>THE ANSWER IS 6</p>
<p>9 works. it doesnt say anything about the same integers..</p>
<p>i know each term does not have to be 1/3...but it CAN BE (it's the easiest way to do it)</p>
<p>12 is a correct answer</p>
<p>@stanford_dreamer</p>
<p>(1/3)=6/18
(1/6)=3/18
(9/18)=9/18</p>
<p>(6+3+9)/18
18/18
1</p>
<p>oh wait, i guess there are multiple solutions... my bad... LOL</p>
<p>and also, how can the diameter vary? circumference = diameter x pi
pi is always constant, diameter has to be constant</p>
<p>i think i put 1 circle for that... is that correct</p>
<p>jaime...i made a mistake, my bad. your solution works</p>
<p>ya bobob, 1 is the correct answer for that one.</p>
