Math question help?

w+x+y+z=81

5x=w
5y=x
2y=z

what does x equal???


I got 14.464 and thats wrong apparently, the answer is supposed to be 5. how does that work?

If you check your work, only x=5 works. It's so confusing.

it was from another question, i tried it but it didn't work in the equation, is the equation wrong, am i not supposed to solve it mathematiclly

Of course, I am talking about weightlessness in a gravitational well, such as Earth's. When astronauts are in orbit, they are essentially high above the earth. Without propulsion, they'd ultimately fall back through the atmosphere. With propulsion, they are able to keep their altitude. Does this continous free fall create the illusion of weightlessness?

I know this might be a stupid question. This is just out of curiosity.

Does anyone know how to calculate a Moment-Axial thrust (M-N) capacity curve for a plain (unreinforced) beam. I'm working with BS 8110 but I think the calculations will be the same irrespective of which code one uses.

Okay, first off, I'm very seldom right, so this is seriously bending me out of shape. This guy I'm dating told me that the little Dipper is comprised of some of the stars in the Orion constellation, and I said no, that Polaris (which is in Ursa Minor) was not part of Orion. Who is right? Please give me stats, not just "you're right", "he's right" Serious answers only, please.
