<p>how did you get 4?</p>
<p>for the infinitely many one i think it was whatever one made both equations equal 6 (the one was just the other times 2) if they werent equal u could do a system of equations and solve, therefore the second one=6</p>
<p>with the infinite solution one it was like 2x-3y=6 and 4x-6y=2a but i didn't what would give infinite solutions, does that mean it can be graphed or something</p>
<p>was the answer for the stamps 13?</p>
<p>Yeah, so it's 3, not 4...</p>
<p>The percent one I got like ~60%, the highest # there.</p>
<p>I got 4 on the infinite solutions one. That way, the bottom equation is just the top one multiplied by two.</p>
<p>i got 2 for the infinite solution because it was 3a not 2a. and for the percent increase, i got 4%, because if u plug in numbers you get 4 percent.</p>
<p>if 4 made the second one equal 12 then its right bc then it would be the top equation if u divide by 2</p>
<p>hey on the one about the boat and the north east thingy, was it 52 ( it was like 5X) cant remember the x</p>
<p>anyone remember the answer to the geranium question....something about how many weeks the geraniums grow to the same height? I think i got 3 weeks</p>
<p>6 weeks.</p>
<p>What was the one with the kilowatts are the old and new price or whatever.</p>
<p>i think i got 19 for the distance to the boat</p>
<p>anyone get a=1/2 for one of the questions with an equation...?</p>
<p>it was 6 weeks, 3 weeks wasnt a choice</p>
<p>ok yea, i see what i did wrong there. it is 4 not 2. btw, wat did you guys get the for the percent increase? it was like last 4th last question or something. i got 4% increase. can someone confirm that?</p>
<p>i remember getting 1/2 for something.....</p>
<p>what did you get for the angle question where you had to use law of cosines i think i know i used 160 for the angle</p>
<p>Did anyone have a problem with one of the ?s ? For some reason, a teacher came in during the math and said "don't answer 46, if you want you can guess." i guessed but i didn't really look at it since i was kind of rushing but it seems like no one else had the same problem...</p>
<p>sk8bro, i dont remember what i got for it, but i remember the angle was 140 degrees not 160.</p>
<p>lolpol, 4$ is not right. It was 57 I think. I just plugged and chugged the answers.</p>
