<p>I have an old blue book, not sure which year, but i got it second hand. It’s the one that on the front that says #1 Best seller. And is either from year 2005 or 2006 because it lists test dates of Jan 28,2006 April 1, 2006, May 6, 2006, June 3, 2006.</p>
<p>I would like answer explanations in a PDF i guess. But I have some specific questions here:</p>
<p>1) If 2|x+3| = 4 and (|y+1|)/3 = 2, then |x+y| could equal each of the following except</p>
<p>A) 0
B) 4
C) 8
D) 10
E) 12</p>
<p>2) Square Root of (x^2 - t^2) = 2t - x</p>
<p>If x and t are positive numbers that satisfy the equation above, what is the value of x/t?</p>
<p>bump- please explain answer :</p>
<p>2|x+3|=4
|x+3|=2
x= -5, -1</p>
<p>(|y+1|)/3 = 2
|y+1|=6
y= -7, 5</p>
<p>A |-5+5|=0
B |5+(-1)|=4
C |-7+(-1)|=8
D not possible.
E |-7+(-5)|=12</p>
<p>5/4…
x^2-t^2 =(2t-x)^2 ------> sq. both sides.
x^2-t^2 =4t^2-4tx+x^2 ----> expand the right equation
subtract x^2,u get -t^2=4t^2-4tx
divide t’s ,add t^2’s , u should get
4x=5t
x/t=5/4</p>
<p>Thanks.</p>
<p>I’m really stuck on this writing problem :</p>
<p>2) The quality of multivitamin tablets “is determined” by “how long” “its” potency “can be protected” by the manufacturer’s coating material.</p>
<p>-the answer is “its”, why?</p>
<p>Isn’t ‘quality of multivitamin tablets’ a phrase, so it should be “its” and not “their”. How am I supposed to know that I should be referring to ‘tablets’ instead of ‘quality’?</p>
<ol>
<li>it looks like a^2+b^2=c^2 huh?</li>
</ol>
<p>sqrt(x^2-t^2) looks like a side of a triangle. lets use the 345 triangle. x=5(hyp), t=4(side)
sqrt(5^2-4^2)=3
2(4) - (5)=3
x/t=5/4
viola!</p>
<p>ask yourself, is it quality’s potency or tablets’ potency? ;)</p>
<p>Is it a safe bet in sentence corrections, that if it asks you to correct the beginning of a sentence, that the subject should always come first?</p>
<p>I.E.</p>
<p>Enzymes are among the oldest known chemical compounds, as they actually are nonliving protein moles.</p>
<p>The correct answer is Enyzmes, among the oldest known chemical compounds, actually are nonliving protein moles.</p>
<p>But I chose Among the oldest known chemical compounds, the nonliving protein molecules are actually called enzymes.</p>
