  1. Which can also be written as (xy)2.
  2. Where did you get that equation from? Work it through: 9x + 81 = 10x + 100 x = -19 Which obviously isn't right and you've lost the y's... 9x + 81 = 10y +100 Substituting for x and y gives: 81 + 81 = 100 + 100 162 = 200 Which also obviously isn't right.
  3. No, it isn't. Trust me. Did you actually read my post? If you have xy2, ONLY the y is being squared. As JT says, that means it can be rewritten as x * y * y. It's really not difficult...
  4. Because it's y2 which is y * y. 32 = 3 * 3 = 9.
  5. The type you describe are some of the easiest you can come across as you're basically given the answer. All you need to do is substitute the numbers given (x=9, y=10) into the formula given (xy2). The only thing you need to remember is what to square. In this case if you were to write the formula out slightly differently you'd have x * y2 Noting that only the y term is being squared. Substituting x=9 and y=10 gives: 9 * 102 Which becomes: 9 * 100 Which = 900. Edit: Not entirely sure how your teacher will have turned it into a proper equation without introducing another unknown (lets say z). In this case we can write z = xy2 Because we know x and y we have one equation and one unknown (z) which means we can solve it. So following what we did before: z = 9 * 102 z = 900. You can always check these things by going backwards. If we pretend we don't know what y is we can start with the same equation as before: xy2 = z So if we first rearrange for y: y2 = z/x y = squareroot(z/x) And now substituting z = 900 and x = 9 into that we get: y = squareroot(900/9) y = squareroot(100) y = 10 Is that taking it too far?
  6. Yup- been sitting in my bedroom in Scotland for the past 5 or 6 years and was delivered to my new house by mum and dad just after Christmas. Have also got my more recent 221Pr frame so was thinking of making a little Monty shrine in the garage!
  7. No worries. If you need a box ask at your local Hellfrauds- they usually have loads of boxes from sold bikes that they'll be more than happy to give you.
  8. That's a bad example though. Gary's been riding mototrials professionally, at an International/World class level since he was about 6. That's a ton of basic balance and technique to transfer to push bike trials. Stick with it and you'll get there!
  9. You're pushing too hard if you're falling off and hurting yourself. Get the basics dialled and learn the simple skills first before working up. By getting things wrong low down you'll soon learn the cat like reflexes that only come with time riding and have saved me from almost any serious injury in 13+ years of riding. Edit: Exactly.
  10. Pretty sure the answer is no... The only time when two minus signs make a positive is when you have the two signs together. For example 4 - 1 = 3. But if you have 4 - (-1) ( read as four subtract minus one) then the two minuses combine to become an addition. So 4 - (-1) = 4 + 1 = 5 Going back to equations lets make everything negative to show how it works. Start with -4x - 6 = -14 We want all the x's on one side and all the numbers on the other so to get rid of the -6 on the left we add 6 to both sides: -4x - 6 + 6 = -14 + 6 -4x = -8 We can now find x by dividing both sides by -4, to leave just one positive x on the left: -4x/-4 = -8/-4 x = 2 Does that make sense?
  11. Looks like most Giants are around the 30.8/30.9mm mark. As Luke says, you just need to buy a shim.
  12. As an alternative to what Jason wrote, and in line with the direction you're going for: 9x+ 21 = 5x -4 Subtract 5x from both sides: 4x + 21 = -4 Add 4 to each side (if you subtract 4 from each side you wouldn't be helping to simplify the problem): 4x + 25 = 0 This can then be rearranged by subtracting 25 from each side: 4x = -25 Which gets you back to x = -6.25. Edit: Also, how did you manage to end up with 14.25 when you divide 17 by 4?!
  13. In equations, the terms (either a number, letter or combination of both) are given a sign (either positive or negative) which is initially 'attached to the term'. In the above equation in JD's post there are three terms: -2, +5x and +63. Addition and subtraction don't really come into it until you start manipulating the equation in order to solve it. Edit: Subtraction is an operation. Something being negative is different and you need to identify the difference between the two.
  14. Think about it... ignore the x's for now. -2 + 2 = 0. It doesn't equal -4 does it? The negative sign before the two is attached to the term in the equation so you are adding 2 to minus 2.
  15. 563g, £125 and rather ugly to boot? No thanks.
  16. Really? Last time I checked neoprene isn't the most supportive of materials. Seems to be designed as a more rugged alternative to wetsuit boots for canyoning and stuff... Not convinced they'd be man enough not to fall apart in 5 minutes if ridden in. Could be wrong though!
  17. Balls. Forgot the clocks went forwards so just joined 28 laps in... Did I miss much?!
  18. Lewis is confident he can 'bring it' to Vettel but I'm not convinced. With a bit of luck McLaren will at the very least have got their act together and won't be screwing things up through crap pit decisions this season...
  19. It's not that old... Looks more like a 99-00 one. Still got my frame in the garage .
  20. I ran the 221Pr forks on my mod for about 4 years with absolutely no problem whatsoever. I sold the bike at the end of last year As far as I'm aware they're still going strong after 4.5 years on the go.
