<p>lies it was b…if you plugged in the numbers to the original equation it made sense</p>
<p>I’m pretty sure the bass player one was add 6.
Initially: 54 bass and 36 percussion (3:2)
Final: 60 bass and 30 percussion (2:1)</p>
<p>idkhur it was b.</p>
<p>if you isolate y and graph it you get (-2/5, 3) which was b.</p>
<p>y-6+5x-11=3+/-sqrt(-5x-2)</p>
<p>graph that and see what the vertex is</p>
<p>nah you add 18 bass and then you have 72 to 36…</p>
<p>Yea ik it was b lol I was saying lies, it was b…I was saying alexmass was wrong</p>
<p>idkhur thats once again what i got. it was saying you add x tot he total number add 18 you have 72 to 36 or 2:1</p>
<p>I guess you’re right, I thought there still had to be a total of 90…oops</p>
<p>no, I believe the answer was 60 to 30 because:</p>
<p>90 players total
3:2 ratio gives 5 total
90/5 = 18, which gives a ratio of 54:36</p>
<p>90
2:1 ratio gives 3 total
90/3 = 30, which gives a ratio of 60:30, meaning you’d have to add 6 more players</p>
<p>you would have to add 6 more brass players if you were going to keep your current players and get a 2:1 ratio. pretty sure Hula is right</p>
<p>I got 45 or whatever e was. What I did was took the 180 TOTAL members and divided it up into a 3:2 (for every 2 percussion you get 3 brass) ratio then used the numbers from that to put it into 2:1</p>
<p>anyone know what the calc one was?
i got (x(x)(x-7)) +5x + 1 but someone said 5(x) is a third multiplication.</p>
<p>anyone know what the answer was? Hopefully my 36 doesnt end on #59</p>
<p>yea my 36 is counting on that calc one too…everything else im 99% sure was correct</p>
<p>Ethanking,
I put that too because none of the other answers made sense</p>
<p>Does anyone remember the wording of the bass player question?</p>
<p>Jay, I think this is it:
3x + 2x = 90
x = 18</p>
<p>54:36</p>
<p>You’re adding people to the overall team, not just to brass section or percussion section.</p>
<p>So when you add 18 you get 72:36 = 2:1.</p>
<p>The question said that there were 90 players in total. The previous ratio was 3:2, brass to percussion. If they wanted to achieve a 2:1 ratio of brass to percussion, then they would need 6 more players.</p>
<p>90 players total
3:2 ratio gives 5 total
90/5 = 18, which gives a ratio of 54:36</p>
<p>90
2:1 ratio gives 3 total
90/3 = 30, which gives a ratio of 60:30, meaning you’d have to add 6 more players</p>
<p>you would have to add 6 more brass players if you were going to keep your current players and get a 2:1 ratio. pretty sure Hula is right</p>
<p>they didnt say how many you had to take from percussion to get the ratio, they said they were added meaning it was 90+x</p>
<p>i think for the calc one it was x(x(x-7)+5)+1
and i got 18 for the bass player</p>
<p>It asked how many brass players had to be added, not how many percussion players had to be converted to brass players…</p>
<p>^ Yep, that’s how I did it</p>
<p>@ethanking</p>
<p>yeah you’re right, they didn’t say anything about how you had to take some from percussion, so you simply add 18 to get the 2:1 ratio</p>
<p>Did the question ask if they wanted to keep less than 90 players? If the question did not ask to keep under 90 players, then 72:36 would be correct. As far as I understood, they didn’t want to have more than 90 players?</p>
