<p>yes its 36</p>
<p>-50 <– 86 –> +50</p>
<p>Since 1 of the numbers is the middle number, that leaves 50 on one side, increasing, and 50 on the other, decreasing, hence 86-50 = 36</p>
<p>What was the answer to the |y| - y one… I think I put .5 or .25? I really hope I put .5, because I might have rushed and accidentally put .25 thinking that the question was asking for y…</p>
<p>wait, couldn’t .25 have been a possible answer anyways??</p>
<p>like, if you used -.125?</p>
<p>abs(-.125)–.125 = .25?</p>
<p>.25 was a possible answer</p>
<p>Is there a cumulative list anywhere yet?</p>
<p>@clandarkfire</p>
<p>Nope</p>
<p>I’m seriously freaking out. For the cylinder one, I got 500 all three times I tried it. But 500 wasn’t a choice! They were all like 200, 250, 300, 350, 400. You guys seem to be acting like 500 was an answer!</p>
<p>And I’m 100% sure it was 96pi. Two circles, 270 degrees. 270/360 is .75. So 3/4 of 2 times the area, which was pi(r)^2, with was pi(8)^2, which was 64pi. Double that and it’s 128pi. 3/4 of that is 96pi. Where does my logic fail?</p>
<p>Phew…</p>
<p>Also, can someone tell me if any of these were experimental:</p>
<ul>
<li>two circles overlapping</li>
<li>6x^(3) = 81x^2 or something like that…</li>
<li>the 3600 one…</li>
<li>the cylinder one (I put like 500 as the answer, so idk if that’s wrong…?)</li>
</ul>
<p>@djumper168
Cylinder with 2 open ends, 500 was a choice. (round from 502)</p>
<p>96pi doesn’t take into account the overlap between the two circles, so you have a hole where they overlap.</p>
<p>@reeptas, did you start from first off or dear?</p>
<p>can anyone explain to me the algebra behind the $2.05 and $1.85 soda/pretzel question?</p>
<p>*ivy price of soda= x price of pretzel=y</p>
<p>2.05=x+2y
1.85=2x+y</p>
<p>Add both equations </p>
<p>3.9=3x+3y
3.9=3(x+y)
1.3=x+y</p>
<p>Price of soda And pretzel is therefore $1.30</p>
<p>@ivy:</p>
<p>I made a systems of equations:</p>
<p>2s + p = 1.80
s + 2p = 2.05</p>
<p>s = .55
p = .75</p>
<p>Total: $1.30</p>
<p>@ivyandlemonade</p>
<p>it was something like 2 pretzels + 1 soda = 2.05, 2 sodas + 1 pretzel = 1.85</p>
<p>add them together to get 3 pretzels + 3 soda = 3.90
divide by 3 to get 1 pretzel + 1 soda = 1.30</p>
<p>@ivyandlemonade
i just used 2 systems of equations for that one on my calculator.
im sure there is a quicker way, but my calculator solves systems so its fine</p>
<p>lol, i was thinking the whole time while doing that question…damn those are cheap drinks/pretzels</p>
<p>@ nikanon or beachbumb…do you remember any of the other choices for that* problem?</p>
<p>Can anyone elaborate (or draw a picture if needed) for the Grid-in’s that gave answers of 72 and 78?</p>
<p>For the cylinder problem, does anyone remember what the right letter was (a, b, c, d, e)?</p>
<p>praying so hard for a 740…</p>
<p>if I missed 3 Grid in Questions and 6 MC questions, do I have any hope for a 670+?</p>
