<p>there was a question i don’t remember exactly that says something i think when a number is multiplyed by 3 is also increase 4 , something like that i don’t remember exactly … but the answer was 2 right ?</p>

84

<p>3x = x-4
2x = 4
x = 2 …enjoy :)</p>

85

<p>What was the one that doubled and then was increased by 1. 20th term starting at -1. Was it -1?</p>

86

<p>^ i dont remember such a question ! where was that? can u write the question or formula ?</p>

87

<p>Do Americans have different tests? I don’t recognize any of these problems.</p>

88

<p>The grid in was my exp. I am trying to figure out which one was the exp. cause i did soooooooo bad one on of them can someone give me some of the q’s on the real grid in section. Was the golf ball the real one?</p>

89

<p>jetfan: I got -1 for that problem.</p>

<p>The math section was really easy, hoping for 780+.</p>

90

<p>The grid-in wasnt the exp. unless ur exam was totally different cuz i heard Americans, yes they do have different test, Brolex :)</p>

91

<p>The grid in for the test in the American test*</p>

92

<p>What’s the grid in answer to:
n and k are both positive numbers
n + n = nk
K + k = nk
what is n+k?</p>

93

<p>For the
n + n = nk
K + k = nk
what is n+k?
i got 2 for the answer~ was it right?</p>

94

<p>n+k=4</p>

<p>n= 2 and k=2</p>

<p>2+2=2(2)
4=4</p>

<p>am i right?</p>

95

<p>its 2 +2 so 4</p>

96

<p>couldn’t it also have been .75? for n+n=nk</p>

97

<p>What was the last grid-in? The one with the multiples of 3?</p>

98

<p>Im quite sure that I and II are correct but can’t really remember about the third one.</p>

<p>did it say the mean is over 4 or the mean can be over 4???</p>

<p>If it says over, then I and II would be the answer, and if it says can be, then all of them will be the answer.</p>

99

<p>It IS I and II definitely.</p>

100

<p>multiples of 3 one could have been 17,19,20</p>
