Official September 2013 ACT Math Thread

<p>Discuss math problems here. </p>

<p>What was the a and b systems of equations one?</p>

<p>103/104?? I guessed that.</p>

<p>I don’t remember the actual problem, but since the degrees were the same the answer was the coefficients of the two x^2s divided by each other. I believe it was 102/103.</p>

<p>I got b as 3 I didn’t remember what a was</p>

<p>A was 1 and b was 2</p>

<p>Awesome. Thanks The513. Also, what about the parabola one? I know y = 3, but I forgot how to find the x.</p>

<p>What about number 18? This might sound dumb because it’s so early in the test (lol), but it had a circle and asked which angle was the greatest (angle 1, 2, 3, 4, or 5.)</p>

<p>Wait so nobody remembers if the question involving digging into a hole on Math (#59) that we already said the answer was (v/lw) - d was answer choice E or not? Because I put E, but that correct answer may have been a different choice.</p>

<p>X was equal to 3 if I’m thinking of the right problem, I think. 3 was the axis of symmetry which is an x-value</p>

<p>What exactly was the a and b problem?</p>

<p>Angle 3 was the biggest I think… whichever angle was in the bottom left half near the chord</p>

<p>What did people get for the last three math questions?</p>

<p>I also got Angle 3.</p>

<p>What did you guys get for the set of numbers like the square triangle and circle</p>

<p>The513, I mean the parabola one where you had to complete the square to find the equation of the actual parabola.</p>

<p>I put square outside, circle, then triangle inside of circle?</p>

<p>It was naturals inside of integers inside of rationals</p>

<p>What were the shapes The513?</p>

<p>circle was rational, so that was outside</p>

<p>So for the last 8 ish questions i put all C. How do u think is correct of all of them?</p>
