    Prove Inequality: x,y,z - Solution Needed

    I understand that part I did that but can't get the statement x+y=1

    Prove Inequality: x,y,z - Solution Needed

    how you eliminate z? you can replace z with 1-x-y but can't see what you did

    Prove Inequality: x,y,z - Solution Needed

    The problem is I am not suppose to use calculus for this problem. This is the algebra course

    Prove Inequality: x,y,z - Solution Needed

    I am still working on this problem and has no clue how to proceed from here.

    Prove Inequality: x,y,z - Solution Needed

    It should be proved for all other combinations of x,y and z. Proving only for x,y and z equal 1/3 is incomplete

    Prove Inequality: x,y,z - Solution Needed

    You are right I did that part already and think it's not enough

    Prove Inequality: x,y,z - Solution Needed

    I found this problem the other day, seems interesting but I am still not sure about the solution Anybody can help x, y, z are numbers with x+y+z=1 and 0<x,y,z<1 prove that sqrt(xy/(z+xy))+sqrt(yz/(x+yz))+sqrt(xz/(y+xz))<=3/2 ("<=" means less or equal)
