Answer:
x=35.35
Step-by-step explanation:
If you multiply 
by 10.1 that will cancel out the 10.1s, then since you multiplies one side of the equation by something you have to multiply the other too. So 3.5*10.1 = 35.35. Then since the 10.1s canceled out this leaves us with x=35.35. Let me know if you need any more help.
A]<span>Given that y varies jointly with w and x and inversely with z and y = 175 when w = 5, x = 20 and z = 4.
then
y=kwx/z
where k is the constant or proportionality given by:
k=yz/wx
but
y=175, when w=5, x=20, z=4
hence
k=(175*4)/(5*20)
k=7
Thus the equation is:
y=(7xw)/z
b]</span><span>find y when w = 2, x = 24 and z = 6.
y=(7*2*24)/6
y=336/6
y=56</span>
