<p>@RMIBstudent Yeah I think you’re right. A lot of the math can be solved without getting into the intricacies of the problem, I think.</p>
<p>Ok guys. Firstly. Someone pls tell me the question which had an answer of 70 in the grid ins. Comeon pls. Also secondly how do you think the curve would be. I guess it should be relatively easier</p>
<p>
</p>
<p>It was the first grid in question, about finding an angle knowing a bunch of others based on complementary angles/etc.</p>
<p>Anyone think the curve will be generous?
I have -1 in math. I really hope I can get that 800…</p>
<p>@RMIB</p>
<p>Are you 100% sure the question was difference between 7th and 8th, not 6th and 7th?</p>
<p>Yes. Definitely.</p>
<p>It’s def 20. I used patterns (since it was sequence) and the diff between two successive terms doubled as it progresses. Therefore, if 6th term 5 more than 5th then 7th is 10 more than 6th and 8th is 20more than 7th.
That’s just a less direct way of confirming. </p>
<p>@pkvnlv they can’t all be 5 bc then 6th term would be 0 greater than 5th and it states it is 5 greater.</p>
<p>I had two grid-ins, so I know for a fact that i had a math experimental. I just don’t remember any of the questions, nor do I recall any of the ones mentioned in this thread. Can those who had math experimental please mention any other questions!</p>
<p>another math question-
the average of 20, 28, 36, and 44 is C. for which of the following sets is the average equal to C/2
answer- 10,14,18,22 (C=32, C/2=16)</p>
<p>@heyhihello was that from the experimental?? Bc i remember having that one</p>
<p>@satano, it is not from experimental, bc i had it and my experimental was writing.</p>
<p>Can someone explain how to exactly do the w+x=10 question with the number line?</p>
<p>Was it just guess and check? How did you guys know it was 10 per segment and w started at -10?</p>
<p>^I’m sure I didn’t do it in the most eloquent way possible, but yeah, pretty much guess and check lol. Looking at the answer choices and seeing they were all multiples of 10 essentially made me realize that the common distance had to somehow take this into consideration. The most simple number to have ‘plugged’ in was 10, and luckily, it did end up being the distance the ticks represented.</p>
<p>@MedicalBoy there were 4 spaces between w and x, and 6 between w and y. since the sum of w and y was 20 more than the sum of w and x, you could find that each space is 20/(6-4) and therefore 10</p>
<p>I think it was 3 and 5 but it doesn’t make a difference.</p>
<p>Thanks</p>
<p>Medical boy:
</p>
<p>I’m going to make up the exact numbers and whatnot, but the gist is that, if you have wyx on a number line in that order, you know that w+y = 20 and w+x=50 (for example). Therefore, y+x must equal 30 (because they’re all on a straight line, and y+x is the difference between w+y and w+x). Let’s say x is three ticks past y; each tick must therefore represent increments of 10.</p>
<p>Therefore, if w+y = 20 and there are four ticks separating them, then w must equal -10. Then, just count up by 10s to z.</p>
<p>for the number line use this to find exact answer without guess and check</p>
<p>"@RMIBstudent:
the wxyz im almost positive is 50 because it was like this
w _ _ x_yz
so u can make 4 equations with 4 variables
w+x=10
w+y=30
2(z-y)=(y-x)
(2/3)(x-w)=(y-x)</p>
<p>u get w=-10, x=20 y=40, z=50"</p>
<p>^that’s an interesting way to solve it. So you can either do system of equations or subtract line segments.</p>
<p>was the difference between 7 and 8 experimental</p>

<p>Did anyone get a question asking for the amount of different ways a car can be painted (roof, hood, and door) if three different types of paint are given (Red, White, and Black).</p>
<p>It was an easy questions, and I’m pretty sure the answer is 6, but I rushed through this question and didn’t think it through. I had four math questions and am hoping that this was the experimental section.</p>
<p>Btw, would the writers of the SAT word a question differently? I don’t really remember there being a juice question, but both questions use the same technique.</p>
