<p>the last one with the three equations? was it 4?</p>
<p>I remember a lot of those numbers, Mike.</p>

the 3 equations took a long time but you end up with z=2

No, it didn't!
You only had to add the three, and w, x, and y immediately cancelled (didn't they?).</p>
<p>Im pretty sure that z = 2. You add the first 2, add the last 2, and then you could replace x - y with one of the given equations so that only z was left, something like 3z = 10 - 4</p>
<p>the xy=x+y i factored to y(x-1)= x so you get y= x/(x-1)</p>
<p>for a/3 + b/6 + c/18 = 1
wouldnt 12 also work because a=1 b=2 c=6
so 1/3 + 2/6 + 6/18 = 1
so abc = 1<em>2</em>6=12</p>
<p>i remember free responses
1.25
4
256
4000
62?
13.5</p>
<p>Yea 40 was definitely 40. The question was:</p>
<p>240 Kids go to camping trip. 5/6 of the class know how to swim. If 1/3 of the class takes rock climbing lessons, what's the least amount of people that are taking lessons that don't know how to swim (something like that).</p>
<p>40 kids cant swim, a third of the class is eighty subtract 40 from that and you get 40.</p>
<p>LesOs, that's how I did it too so yes it was quick, although at first I was clueless and spent maybe 5 minutes plugging in x's and w's and y's and z's in a circle.</p>
<p>z definitely was 2....
and mike i got similar free-response to you</p>
<p>thank god the camping question was 40</p>
<p>damn, was it abc or a+b+c?</p>
<p>mike10003, I think I had the same free response answers :) Does anyone know which math was experimental?</p>
<p>what was the question for the answer 256</p>
<p>i got 1<x<2 where xy=...</p>
<p>but what was the answer to xy=x+y? It asked for the correct range of responses</p>
<p>the choices were like x<0, 0<x<1, 0<x<2,="" 1<x<2,="" and="" x="">2</x<1,></p>
<p>you know how it was 3 equations... was it z= the others or another letter = ____. What was the initial letter?</p>
<p>Chinnu twelve as well as nine worked you get 6a/18 + 3b/18+c/18 you set c to nine and a and b to one there fore 3(1) +6(1) +9/18 = 18/18. That works right?</p>
<p>256 = the area of the square with the circle of 16pi</p>
<p>for the one where you had to find the area of the rectangle given a y= equation was the answer 27 or 27/2?</p>
<p>It was 27/2....the x intercept was 1.5, so that was the base, and the height was the y intercept, which was 9.</p>
<p>but if you had y=3 and x=1.8, then xy doesn't equal x+y</p>
<p>maybe I read the question wrong?</p>
