<p>But the question only asked for p+q+r, which equal 125.</p>
<p>i got 136, so I just ended up choosing 140 (if that was a choice). Sciencefrenchie did you take the ACT before? if so, what was your score?</p>
<p>Math was killer.</p>
<p>wanago2college - Nope, today was my first time. Fingers crossed that it’s the only time, and I can be done with standardized tests for the rest of my life (I can always dream, right?) Have you?</p>
<p>blstrs - No, that’s right (the arc was 180 though, not the angle). We were talking about a different problem :)</p>
<p>its my fourth time actually haha. I been from a 22 to a 27, hoping for more. Just curious btw, are you a male or female?</p>
<p>Does anyone remember this question?</p>
<p>If x^6 = 64, then what does (some equation) equal?</p>
<p>Wouldn’t x = 2?? I plugged 2 into the equation and I didn’t get any of the answers. I was stumped, because the right way to do the problem seemed so obvious but somehow I screwed it up.</p>
<p>x=2 or -2.when you square (or put to the exponent of 6) a number it can be negative or positive. So the sum (or whatever the question was) could be 2+2 -2+(-2) or whatever, depending on if x=2 or -2. Does anyone know the answer to the question where the absolute value of A minus A=0?</p>
<p>You had to use -2 instead of 2 for x to get the right answer</p>
<p>wannago2college - watever answered applied to all postive nonzero integers. 1,2,3,4,5. i forgot what the exact answer said</p>
<p>NOOOOOOOOO…</p>
<p>Crap. I completely forgot about x^2 being both positive and negative.</p>
<p>i thought it was all negative and positive numbers. b/c when I plugged in all numbers (pos, neg, and 0) it gave me 0</p>
<p>I think it was just postitive integers and 0, because I know that if you had out a negative number as X and subtracted the absolute value of itself, you would just have a smaller negative.</p>
<p>yea. like say A= -5. -5 minus the absolut value of -5 is still negative. the same for any other negative</p>
<p>oh yes it was zero too. 0 and all nonzero positive integers only. that’s what it said</p>
<p>0 and nonzero positive integers? lawl.</p>
<p>I think we learned a valuable lesson today gentlemen:</p>
<p>DO NOT REPLACE YOUR BRAIN WITH A CALCULATOR.</p>
<p>im glad i was going through cracking the ACT last night and wen i got to irrational, rational, and integers, i wondered - will i need to know this tomorrow</p>
<p>I would have to dispute your answer. The problem is that I cannot remember what the question was. if it was |a|-|a|=0 it would be all integers, pos and neg. If it was a-|a|=0 then I would be wrong and it would be only pos.</p>
<p>the equation was A -|-A|</p>
<p>If A was negative you would be subtracting a postive number from a negative and continue to get a negative</p>
<p>Aww, and i thought id get a perfect math grade. I remember that problem, i breezed through it and put all integers which is wrong.</p>
<p>getoutofmyyard - if it makes you feel any better, I think I spent most of my time on the math section on the stupid x^6=64 one. I did eventually figure it out but not before coming back to it and not without wasting a LOT of time. I got a 36 in math last time, but am not nearly as optimistic this time after reading these replies!</p>
