Can you help me on these kinematic physics problems?

Here are the equations used in this:
Vf = V0 + at
x=x0+v0t+1/2at^(2)
Vf 2 = V02+2a(xf-x0)

where vf equals final velocity
v0 stands for initial velocity
xf=final
x0 stands for initial


Using equation (1) solve for t given that v0=5 m/s, vf=25 m/s, and a=10 m/s^2
Given v0= 0 m/s, x0=0 m and t= 10 s, use the second and the third equation together to find xf.
3.a=10 m/s^2, x0=0m, xf=120m, and v0= 20m/s. Use the second equation to find t.
vf=-vo and a= 2m/s^2. Use the first equation to find t/2.
How does each equation simplify when a=0 m/s^2 and x0= 0m?
