<p>On the dec sat, there was a question about what is x if the two line are parallel. The figure was not drawn to scale. i put x=1.5</p>
<p>On another, what was (r-1) plus s something =zero. I think it was the experimental because it was harder.
I didnt know the answer</p>
<p>One was the man runs a mile in something x and a certain number of miles. What is his speed per mile? something like that</p>
<p>was the answer d? </p>
<p>do you remember any other hard math questions?</p>
<p>I don't remember your question</p>
<p>but I think the hardest one is the paint red cube one... asking how much small one is plain white...</p>
<p>I said 8</p>
<p>I think I'm wrong ;(</p>
<p>@ poster: I put x=1.5 as well, I hope it's right. I didn't really have much time to work on this one, but 1.5 seemed to make sense. Did anyone else put 1.5?</p>
<p>I put x = 1 for the two parallel lines, because</p>
<p>x+3 = 2x -> 4 = 4 </p>
<p>Right? I hardly remember the question</p>
<p>I don't really remember the question either, but why would x+3=2x?</p>
<p>Plus, 1+3=4, but 2(1)=2......how would those both equal 4?</p>
<p>smalllab, you are right. it was 8</p>
<p>@ dplatzz, how sure are you of 1.5?</p>
<p>dpattz, I'm sorry, it was supposed to be "x+3 = 4, 2x = 2, 4 = 2x2" which satisfies the fact that one triangle was double the size of the other. my bad</p>
