Ask Dr. Math is my favorite.  You can also try Mathworld, though I usually find that I leave it more confused than when I entered.

Option a: use one of the fancy calculators around nowadays.\nOption b:\nOk, we need at least a reasonable guess to get going. Lets draw a graph. But how do you draw a graph of 2cos(x) + x? We don't. We draw a graph of 2cos(x), and another graph of -x, and see where they are equal - because thats the point we're looking for. Don't forget to use radians, since you can't add a number to a degree.\nThe solution looks like it is around -1 or so. Now we can do a bit more guessing.\nPutting -1 into that equation gives 0.0806. Lets try -0.9. Whoops - that gives 0.34, which is getting even worse. How about -1.1? Ahha! That gives -0.19, so we know the answer is between -1.1 and -1.0.\nWe can keep narrowing it down in this way. Try -1.05: thats negative, so we're between -1.0 and -1.05. Try -1.02: thats positive, so we're between -1.02 and -1.05. Try -1.03: thats negative, but nearly 0. So we're between -1.02 and -1.03.\nWe're nearly there - try -1.025. thats positive, so we're done! We know the answer is between -1.025 and -1.03, so it must be -1.03 to the nearest 100th.\nThats quite a bit of work, but its not too bad. There are faster ways to do it, but they're a bit more complicated.

Problem 1:\n\n1912.50/45,000 = x/60,000\n45,000x=60,000*1912.50\n45,000x=114750000\nx=114750000/45000\nx=2550\n\nProblem 2:\n(2000/3 = 3300/x)*2\n(2000x=9900)*2\n(x=9900/2000)*2\n(x=4.95)*2\nx=9.9 seconds\n\nThese solutions are solving for x algebraically, but are the long way.\n\nAs mentioned above, an easier way is to figure the percentage of each and then multiply.\n\nSo $1,912.50 divided by $45,000 = .0425.  Multiply this by $60,000 (60,000*.0425) = $2,550.\n\nThe same can be applied to the number of seconds.\nIt takes 3 seconds to print 2000 characters...3/2000 = .0015 (or 1 character every .0015 seconds).  Then multiply this by 3300 to get the time for 1 page = 4.95 seconds.  Then multiply by 2 to get the time for two pages: 4.95*2 = 9.9 seconds.
