Xvaries jointly as w, y and z. if x=18 when w=2 y=6 and z=5 find x when w=5 y=12 and z=13...

234

Step-by-step explanation:

x=kwyz

18=k(2)(6)(5)

18=k(60)

18=60k

x=kwyz

x=234

x = fwyz x = (3/10)(5*12*3)

18 = f(2*6*5) x = (3/10)(180)

18 = f(60) x = 3*180

60 60 10

f = 3 x = 3*18

10 x = 54
