<p>prove to me that 8.5 was the answer.</p>
<p>it said real numbers. I changed it from I, II, III to I, III because I forgot what real numbers meant and had a brain fart and thought it meant whole numbers.</p>
<p>IvyLeague99, did you not read my explanatory post on the problem? X and Y do NOT have to be integers, neither does the average. If you don't believe me, why don't you make a new topic with a poll?</p>
<p>You said "Therefore x + y has to equal 25.5" why does it have to equal 25.5?</p>
<p>2+3+3+6+x+y+20
---------------- = 8.5
7</p>
<p>The question is whether or not the above is possible (I'm doing the problem with real numbers, not integers). </p>
<p>x + y + 34 = (7)(8.5)</p>
<p>x + y = 59.5 - 34.0 = 25.5</p>
<p>I'm pretty sure the problem stated something dealing with integers or whole numbers. I got to X + Y = 25.5 myself, and purposely excluded this as a possibility. I'm positive this was done for a reason.</p>
<p>Nah, it said real numbers. Sorry.</p>
<p>Look on page 244 of the blue book, "the SAT does NOT test complex numbers" It did say real numbers , BUT as The.End said it included integers or whole numbers.</p>
<p>Damn it. I can't remember what it said, nor what I put. uggggggggggg. noooooooooooooooo</p>
<p>whatever guys , we'll see on Feb. 13</p>
<p>gcards, </p>
<p>Trust me, I will bet you anything it said REAL numbers. IvyLeague even agreed.</p>
<p>O.K. Real numbers just means all non-imaginary nubers. Perhaps it was just a way to trick people who thought integers?</p>
<p>It did say real numbers , but asked for a integer value . TRICKY.</p>
<p>the answer had to be I III , because those are the only ones that give whole numbers.</p>
<p>wait, it should be integers for the others, since it'd be too easy. Think about it. It makes more sense to be integers, or else the problem is way too simple with real numbers. I know it said integers. I don't remember real numbers at all. Now, did I put the correct answer?</p>
<p>I think it is I and III.</p>
<p>Well, I still assert I, II, & III but no more arguing from me tonight. I've got to finish these notes then it's time for 24. ;)</p>
<p>Yes, I think it did ask for an integer value or something like that. There was a specific reason I excluded 8.5, and I wouldn't have been fool enough to do that because of the word "real" or "rational".</p>
<p>allright, gcards and ivyleague99 both saw integer. im not positive if i saw integer but i know i saw something that lead me to believe whole numbers. And liek gcard said, if it didnt say integer, it would be WAY too easy. if you could have decimal values than it would quite simply be I, II, and III, you wouldn't even need to do any calculations.</p>
<p>eh..., I really hope Julina is right cause i put I II and III, cant afford to lose another raw pt or two...</p>
<p>I didn't see the word integer. Cross my heart. So i put i, ii, iii</p>
