<p>The 23 days was one about her salary… she made $50, spent $30 total on living expenses (there was some breakdown there), so basically netted $20/day. The question asked how many days it would take to save at least $450. You divide 450/20 and round up to get 23.</p>

<p>The 250 one gave you x^5=50 and y^2=10 (maybe used different variables), and asked what x^10 * y^-2 was. So it’s 50^2 / 10 = 250.</p>

<p>And yeah, I believe it said that the three angles added up to a right angle, not a right triangle.</p>

662

<p>No ^^^ 2x, 3x, and 5x all have to EQUAL 90 degrees. X = 9</p>

<p>EDIT: 18 + 27 + 45 isn’t 180… It’s 90</p>

663

<p>CPU, notice the equals sign with a slash through it.</p>

<p>@not I understand the first two, those were different problems (probably not pertaining to what I said) but what was the three angles problem because it doesn’t make sense to me. Why would three add up to a right angle?</p>

<p>EDIT: I guess I just read the problem wrong :/</p>

664

<p>Some other people asked about the other two problems.</p>

<p>I don’t think the problem was talking about a right triangle. I don’t know WHY it said right angle, but I’m pretty certain it did… unless everybody other than you misread that problem.</p>

<ol>
<li><p>How did you make that slash? Lol</p></li>
<li><p>I know, but when you put 18+27+45 you had = 180
then 90 does not equal 180. You had both equations equalling 180</p></li>
<li><p>That’s what the question was. All three had to equal a right ANGLE. I double checked that question and even drew a picture (of a right angle only)</p></li>
</ol>

666

<p>Alright, that sucks. :stuck_out_tongue: I was just putting all of my steps to show you my thought process. What would -1 (or possibly -2) from the free response give me then?</p>

667

<p>-2 would be 760 or so, depending on the curve. -1 around 780, maybe 790.</p>

668

<p>Certainly not a 800inmath.</p>

669

<p>Yeah :frowning: I couldn’t believe that I would make a mistake like that, it’s not like me.</p>

670

<p>Sharrine- “Certainly not a 800inmath.”</p>

<p>I wonder how you did on the writing portion ;)</p>

671

<p>Well I got an 800 in writing on the March SAT so if I made a grammatical error in the fragment I wrote above then that would be really embarrassing. :P</p>

672

<p>I would recommend Dr. John Chung’s 50 tips for SAT Math</p>

673

<p>Shouldn’t the 14 consecutive numbers be II and III??</p>

674

<p>■■■■■ Sharrine smh -___-</p>

675

<p>Newton I think it was</p>

676

<p>Does anybody remember the problem where it was something like xy=10, yz=5, and xz=2. Find xyz. These probably aren’t the right numbers but I was just wondering if it was experimental or not.</p>

677

<p>@above
its 50
and it’s also on the list we have a couple of pages back</p>

678

<p>Oh my bad, didn’t see it</p>

679

<p>Does anyone know what I would get if I missed 2 gridded, 2 MC(blank), and 2 MC(answered). I ****ed up ._.</p>

680

<p>My guess would be 720, or anywhere from a low 700 to a high 600.</p>
