<p>Ya its 6 because 3(1)+2=5 and 3(1+2)+2=11,w=1, 11-5=6</p>
<p>I just plugged numbers in for that but think I got 6 as well.</p>
<p>for A/8 + 2/9 = B/72</p>
<p>I put 34, but just wanted to discuss any rationale behind it…</p>
<p>cross multiply…you get 9A/72 + 16/72 = B/72
so, B must be 16 + 9A…
16 + 9(1) = 25
16 + 9(2) = 34 ?
and so on</p>
<p>@qqqrt Seems logical.</p>
<p>I think I put A for that question though, so if that’s not what option A was, my brain must’ve been fried haha!</p>
<p>Anyone know if the contrapositive question was experimental? The one about if its in x, its in list y</p>
<p>Bear: nope, I think it was real.</p>
<p>it was C. if it is not in list y it is not in list x</p>
<p>Phew i got it then. Someone earlier said it was if not in x, then not in y.</p>
<p>how were you supposed to recognize how to find the answer for the question where you had to choose which of the cube shapes wouldn’t fold into a perfect box? I have a hard time imagining 2D figures shaping into 3D and guessed the wrong answer</p>
<p>can someone describe to me this red car salesman problem?</p>
<p>Did anyone get some question abaout 10K + V = 16???</p>
<p>I put 10V + K = 61</p>
<p>because in 10K + v = 16, K = 1 and V = 6, 10(1) + (6) = 16</p>
<p>so 10V + K = 10(6) + (1) = 61</p>
<p>???</p>
<p>I guess also saying that K and V were digits on a two digit number was their ‘tricky’ way of saying that they were integers. I actually almost omitted it</p>
<p>@Thomas
I also got 61. But it might have been experimental. Anyone confirm?</p>
<p>Yup I got the 10K+V=16 question. Only integer replacements for K and V are 1 and 6. Then it’s asking how to modify the equation to get 61.</p>
<p>Clearly, it’s 10V+K=61.</p>
<p>did anyone get the median for the first 101 odd integers problem? i put 101 but as a guess.</p>
<p>For the 10K + V = 16 one, if they’re both digits of a number, they’re both less than 10. So 10K would put K in the 10s place and then V in the ones place. So K = 1 and V = 6. So to get 61, it’d be 10V + K.</p>
<p>Can anybody please a compiled list of the question + the answer</p>
<p>does anyone remember a problem where you had a set of numbers, i think 100 to 399 inclusive, where your hundreds digit had to be odd and the tens digit had to be even and they asked how many possible numbers there were? i had experimental math so it could have been in that section.</p>
