<li><p>Make a proportion. 8/12=6/x x=9</p></li>
<li><p>x=2 so x^3=8 So the correct asnwer is B) 2x+x^2=2*2+2^2=8</p></li>
<li><p>The answer is B) 7/8 or 0.875 The distance between P and Q is 1.5 so 1.5/4 is 0.375. Hence, 1/2+0.375=0.875 or 7/8</p></li>
<li><p>The answer is E). v=7x^2/6 Just plug in values in answer choices to your calculator and see which result gives you a positive integer. Only E) does.</p></li>
<li><p>The answer is A). Just make the equation: 18.5+3.5x=20.5+2.5x Hence, the x is equal to 2. And 4+2 is 6.</p></li>
</ol>
<p>1) similar triangles. C.
2) plug in 0 fot ‘n’. B.</p>
<p>3).
2-1/2 = 3/2
(3/2) / 4 = 3/8
3/8 + 1/2 = 7/8</p>
<ol>
<li>Plug in the second equation to b. It becomes 7x^2/6
since 7 cannot be divided by 2 or 3, you can only plug in a miltiple of 6.
So plug in 6 for x. You get 42.</li>
</ol>
<p>Well 3 is B… There is 1.5 between P and Q… Multiply .25 by 1.5 and then add that number to .5 …it comes out as .875 which is 7/8</p>
<p>Number 3 is 7/8. Distance from 1/2 to 2 is 3/2. 1/4 of 3/2 is 3/8 and 3/8 plus 1/2 to get the other coordinate is 7/8.</p>
<p>5).
The equations: 3.5x+8 and 2.5x+13
Find a point where they equal.
It’s x=5</p>
<p>So the answer is 6 hrs. My bad. I didnt look at the answer choices.
If u plug in 0, which is really 1, you get 8.
so since you see that u have to add 1 to whatever value you get, you should add 1 to the 5 you got earlier.</p>
<p>thx so much…u guys r gr88! :)</p>
<p>@Mirage2000 i think in number 1 u meant to say 9/12=6/x so x=8 ;)</p>
<p>and in number 2 i didnt understand very well!</p>
<h1>5 is B. Product A can be shown as the equation 3.5x + 8 and product B can be shown as 2.5x + 13.(2.5 and 3.5 are the flat rates per hour for each product). Set these equations equal to each other and solve for x.</h1>
<p>1x= 5</p>
<p>Yes, it was 8!
2) I did it with calculator so maybe someone can explain better.</p>
<p>@Golfguy when i solved the equation the answer will be x=5 so y would the answer be choice B ?</p>
<p>@Mirage2000 no problem anyways thx soo much :)</p>
<p>Golfguy,
B is 7.
5 is not an option.
You have to add 1 to the vale you get. Because f(0) is the 1st term. Which means f(5) is the 6th terms. We found that x=5. so it is the 6th term.</p>
<p>Or just plug it in.
3.5(5)+8 = 26.5
2.5(5)+13 = 26.5</p>
<p>it is definitely the sixthterm. So the answer is A.</p>
<p>For #2,
if you look at the right side of the equation, it says x^(n+3)
and the question is asking what is x^3.</p>
<p>So… If u plug in 0 for ‘n’, you will get a x^(0+3) which is x^3.</p>
<p>And of course, you have to plug in 0 for n’s on the left side too</p>
<p>@dhs911230 yaah u r right about #5 we must add 1 cuz 0 is the 1st term.</p>
<p>and thx about #2 it is really an easy way to solve the question :)</p>
<ol>
<li>The pic is not showing on my cell :D</li>
<li>B</li>
<li>B</li>
<li>E</li>
<li>A
And I’m 2 lazy 2 type how I did those :D</li>
</ol>
<p>you don’t have to plug in numbers in number 5</p>
<p>8 + 3.5(X-1) = 13 + 2.5(X-1)
3.5 (X-1) - 2.5(X-1) = 13-8
X-1 = 5
X=6</p>
<p>BallsBalls,</p>
<p>That’s basically the same thing.</p>
<p>i just think plugging in number can be more time consuming considering you don’t want to waste time in the exam</p>
