Explanation for Question 16 From the Math (Calc) Section on the 2019 April Sat
So for number 16, it gives us this equation here and then defines all 2 the variables P peanut row G and H. 3 And then it is asking what is H in terms of P P not 4 row LNG. So we are basically taking this equation and rearranging 5 it so that we end up with H equals some collection of variables. 6 So I would go ahead and rewrite it down here so we can start 7 working towards isolating our variable H which is right 8 here. So the easiest thing we can get rid of is probably the peanut. 9 So we can subtract it from both sides that 10 leaves us with P minus peanut equals row G H. 11 So now here's our age again, what we are trying to isolate and H 12 is being multiplied by P and G. 13 So in order to get rid of multiplication, 14 we can divide it from both sides. 15 So if I divide by row G on both sides, 16 that'll get rid of the G and the row. 17 And that leaves him with P minus peanut overrode G is 18 equal to H so the correct answer is 19 B.
