Explanation for Question 5 From the Math (Calc) Section on the Official Sat Practice Test 6
Question five gives us this expression, 2 six X minus nine, Y is greater than 12. 3 And then it asks us which of the following inequalities is equivalent to the 4 inequality above. So after writing it out, 5 if you take a look at it and hopefully you can see that each 6 term here is divisible by three, 7 so we can divide both sides by three. And that's a lot because if 8 you do the same thing to both sides, it's still the same expression. 9 And we get six divided by three is two X minus nine, 10 divided by three is three. Y is greater than four. 11 Okay. So let's take a look at our answer choices and see if any 12 of them match up and they do so we can pick B as our 13 answer choice here. We've got two X minus three, 14 Y is greater than.
