Please help me. I can't figure out this math problem. I have an idea, but I don't think its right at all!


w + x + y + z = 24
3w - 2x - 3y + 3z + -9
5w + 3x - 2y -2z = 4
2w + 4x + 4y - 5z = 22
Find x, y, w, and z.

Creative answers are welcomed. Go where your imagination takes you.

If you don't want to live on any of the moons just tell me which High Street shop you find best for clothes shopping.

Or how many apples you can fit into a barrel of jam jars.

pick a number between 3 and 100, divide the number over 3,5 and 7 seperately, from the three reminders you should be able to give the earlier picked number.

ex.

if we picked 26
26/3 = 8 with 2 remaining
26/5 = 5 with 1 remianing
26/7 = 3 with 5 remianing

if the numbers 2,1 and 5 are given as reminders for 3,5 and 7 respectivly, is there a systematic way, formula to find the picked number (26 in this example) i have a solution but i couldnt put it in a mathimatical shape, so i will post it if i didnt get a solution !

I have to do an experiment about density. we have to find an object the will sink to the bottom of a tub filled with water (about a foot or so of water) and then after exactly one minute of staying on the bottom it has to float. Our teacher suggested something that gives of a gas (non toxic) or something that will decrease in mass or increase in volume. the density has to change for it to be able to float... any ideas.... i was thinking of tying an object to a sugar cube but i haven't tried it yet and i would really like other ideas...

Assume the big bang occurred out of nothingness. Particles were blown in all directions. But, what if the "explosion" first faced away from us, scattering particles away from us. How could we ever see that light? Isn't it possible that some particles are travelling faster than those we can see (that is those aimed in a different direction than us?
