<p>What was the one math with x-t and the choices were 15, 10, 5, -10, 15?</p>
<p>i think it was 217…lol</p>
<p>i think 15</p>
<p>it was 15, add the equations</p>
<p>I think I got 15 for that one.</p>
<p>@collegegrabber:15. you just add the equations…</p>
<p>Wasn’t it x+y = y+z = z+t = 5?</p>
<p>Might have been a minus somewhere in there.</p>
<p>Find x-t, given x-y=y-z=z-t=5</p>
<p>Oh right, they were subtracted.</p>
<p>For that I found that if you added all three together then the y’s and the z’s canceled and you had 15 from the three equations adding together.</p>
<p>So is the general consensus that “achieve it” was incorrect? (So writing no error would be wrong?)</p>
<p>yeah i found it easiest to just separate the equations</p>
<p>x-y=5
y-z=5
z-t=5</p>
<p>Solve for X, Y, and Z respectively. Substitute.</p>
<p>^^
Yeah, “achieve it” was the error. </p>
<p>Does anyone remember a question about environmentalists or something? Or am I thinking of a practice test?</p>
<p>cc123sb: that’s what I did, but I just realized that you can do it faster by adding the equations. y and -y cancel out, as do z and -z. Then you get x-t=15.</p>
<p>argh, i was on the fence on that one.</p>
<p>@chillbro
yes i remember one about environmentalists, it was in that reading passage about privacy. the first author was recalling another “environmental crisis” about big business poisoning the rivers</p>
<p>What did you guys get for the math one that involved 2 and -1?</p>
<p>Does anyone remember if they got the canada question as no error. Also, the hands were affectionate, not soft.</p>
<p>^-2 was it</p>
<p>@1995Andrew</p>
<p>how can a hand be “affectionate”
it was soft as it was comparing it to Uhmma’s hard, calloused hand</p>
<p>Andrew: I don’t think it was affectionate, because it was contrasting the narrator’s hands with her mother’s. Her mother’s hands were affectionate, but not soft.</p>
