Math grade 9 and up
x/s + y/w = 1 s/x + w/y = 4 You can use substitution. From the first equation, wx + sy = sw x = (sw - sy)/w Substitute to the second equation: s/x + w/y = 4 sy + wx = 4xy sy + (w)((sw - sy)/w) = 4((sw - sy)/w)y sy + sw - sy = 4y(sw - sy)/w sw^2 = 4swy - 4sy^2 4sy^2 - 4swy + sw...

tensionbottom=mg+mv^2/r solve for v. force on set must equal tension... b.total acceleration is a vector of g downward, and mv^2/r along the radial. but tension alone, along the radial, tension=mgcosTheta+mv^2/r but tension and gravity force=net force net force=mass*...

5th grade math
h+f = 120 h+p = 230 p = 6f h+6f = 230 h+6(120-h) = 230 h+720-6h = 230 -5h = -490 h = 98
