<p>"2x + by and 2x + 10y parallel one? "
i think i got 2.</p>

<p>^the answer was 10</p>

<p>Did anyone have a question that was like: at what time will A and B be at the same time? or something like that? one was 4 hours and the other was 6??
it was section 2 for me i think</p>

<p>“3x=6- 17”</p>

<p>sorry, what was this question again?</p>

<p>^ sucks for me.
how did you figure it out to be 10?</p>

<p>iliketodance123 im pretty sure experimental</p>

<p>@ ewaffles, no you are reading it wrong; the question had 3x=6 in it and the answer is 17.</p>

<h2>it was section 2 for me i think </h2>

<p>I think they started a 10AM, one 4 hours, one 6 hours. LCM is 12 hours. So I added 12, said it was 10 PM the same day.</p>

<p>Someone verify.</p>

<p>^ ahhh im so confused now.
i thought that my section with the logic question (not the one with what test did she take and when) was experimental, but i dont think it was in the same section as the one i just described.
this is driving me insane.</p>

<p>^ sucks for me.
how did you figure it out to be 10?</p>

<p>i took the second equation, put it into slope-intercept form… the slope turned out to be -1/5… then put first equation into slope-intercept and it was by=-2x+(some unimportant number, lets say 5)… so what number would b have to be for -2/b to be -1/5…10</p>

<p>OH GOOD!
thats what i got too… 12.
i hope that section was not experimental.
did you have anothe rmath section for section 3 too?</p>

<p>i meant 10 pm the same day^
so yeah, i got the same answer</p>

<p>@gaoez, do you remember the question? cause i don’t remember putting 17 for anything… ugh hope i didn’t do something stupid…</p>

Triangle problem with a 140 degree angle, asking for top angle- 90 degrees</of></x<2></p>

<p>Thanks for keeping the list updated, Bigb.</p>

<p>np, can anyone confirm the last one I just added, the 90 degrees?</p>

<p>yes, 90 degrees for that one
And there was a logic problem, somethign about studying for a test.
I think the answer was “if he failed, then he did not stufy for the test”</p>

<p>The logic one was part of an experimental section. We’re not including it in the list.</p>

<p>does anyone know what section that logic question was in for them?</p>

<p>90 degrees %100 percent sure</p>
