  1. (2x + 1) - t;  (2x + 1) - 6 = l


  2. They taught us how to answer these sort of questions back in middle school.... there is no answer...however they were one centimeter taller / shorter than each other... is that right?

  3. Dont Know It was Dark after The Candles were OUT !!

  4. Easy way to do this is that the long candle is lit for a total of 6 hours, the short candle is lit for a total of 4 hours. That would mean the one centimeter difference takes 2 hours to deplete. Therefore one centimeter is burned off every two hours, or half a centimeter an hour.

    Since the long candle takes 6hours to deplete that means it was 3 centimeters long. Since the short one was 4 hours to burn out that means it was 2 centimeters long. It fits; the long one is 1 centimeter longer than the short one.

    Edit: I misread "blown out" as burned out, didn't have my contacts in. Therefor, no real answer is discernible.

  5. I'm no good at math.

  6. 8 & 9 cm!

    this is what my brother told me to write hahah

  7. nothing left?

  8. is one shorter thn the other?

  9. The length is unknown because it was never told. Alls we know is that one candle is 1cm taller than the other.

    Trick question ;)

  10. there is nothing

  11. You cant tell by this information. Not enuff info.

    However, The longer candle lost 4cm. and the other lost 2/23 cm.

  12. One is longer by a centimeter; there are no other measurements except time

    The burning time (length) of the long candle is 6 hours and the burning time of the short candle is 4 hours

  13. They are the same length...

    please i tried!!

    BEST ANSWER ME!! =D...porfavor

    please

    si vu plez

  14. the same length?

  15. Suppose X is the length of the LONG CANDLE & it's Burning Time is V1

    And Y is the length of the SHORT CANDLE & it's Burning Time is V2.

    We know that : Y = ( X-1) .

    AT 16:00 hrs :

    X - 4*V1 = Y - 2.5*V2

    After substation Y with ( X-1) :

    (4V1 = 2.5V2 + 1 ............................. (1

    After blowing out the candles :

    (X = 6 * V1 .................................... (2

    (Y = 4 * V2 ................................... (3

    After substation Y with ( X-1) :

    (6V1 = 4V2 + 1 ............................. (4

    And from 1&4 we find that :

    (V1 = 1.5)  & (V2 = 2)

    Then we substitute in 2&3 :

    (X = 9 cm)

    (Y = 8 cm)

    The Long Candle at the beginning is : 9 cm

    The Short Candle at the beginning is : 8 cm


  16. its right back to the answer

    the long candle is bigger than the short one by 1cm

  17. Before: one was 1 cm longer than the other.

    After: one was .5 cm shorter than the other.

  18. they were blown out how can i tell?

  19. hard one

  20. the same? idk! to hard!!!
