Question 179072: I greatly need your help. In trying to solve the problem. I found out that the hits are 25,000x24+110,000=710,000 hits. I'm having a hard time trying to set th prblem up as a proportions. Will you please help.
An administrator of a popular web site is told that a new faster server, which will replace the old server, can handle 45,000 "hits" (users accessing the site) per second. The web site currently experiences a peak demand of about 110,000 hits per second. But, every month, the peak demand increases by 2500 hits per second. Use a proportion equation to determine how many new servers the administrator should buy to address expected traffic for the next 24 months.

Question 184903: Asking for some gentle guidance please.
Solve each equation. # 43 on page 147.
0.5x+2 2.25x+27
_______ = _____________
3 9
In case this looks bad.... 0.5x+2 OVER 3 = 2.25x+27 OVER 9
I have done the following:
9(0.5x+2) = 3(2.25x+27)
Do I need to move the decimals? It does not seem to matter thus far in getting the correct answer. I know to cross cancel but with the decimals I am getting a tad confused perhaps.
4.5x+18 = 6.75x+81
Subtract 4.5x from both sides
18= 2.25x+81
Subtract 81 from both sides
-63 = 2.25x
Divide -63 from both sides
and I get the wrong answer which I hope you see what I am doing wrong!
The answer is to be {-28}
I am over thinking this I am sure and it is late. I shall leave this and hope for a pleasant, helpful push in the correct direction to solve this in the AM.
Thank you for your time and help!
