False.

Example:
x = 10
y=2
z = 3

x/z is 10/3, so x is not divisible by z.
x / (y+z) = 10 / (2 + 3) = 10/5 = 2.

False, there are many counterexamples to be found for example:

if y=1 x=9 and z=2

9 is not divisible by 2 but when you add 2 + 1 you get 3 and 9 is divisible by 3.

False, if z=0, then x is not divisible by it, and if y is not 0, then x is divisible by (y+z)
