Let's evaluate each expression step by step based on the given values of the variables.

1. Evaluate for x = 4

- $ x + 16 = 4 + 16 = \boxed{20} $
- $ 2x - 20 = 2(4) - 20 = 8 - 20 = \boxed{-12} $
- $ 10 + x^2 = 10 + (4)^2 = 10 + 16 = \boxed{26} $
- $ -x - 12 = -4 - 12 = \boxed{-16} $
- $ x - 2x = 4 - 2(4) = 4 - 8 = \boxed{-4} $
- $ x^3 - 20 = (4)^3 - 20 = 64 - 20 = \boxed{44} $

2. Evaluate for h = 3

- $ 3h + 9 = 3(3) + 9 = 9 + 9 = \boxed{18} $
- $ 19 + h^2 = 19 + (3)^2 = 19 + 9 = \boxed{28} $
- $ h + 14 = 3 + 14 = \boxed{17} $
- $ -2h + 14 = -2(3) + 14 = -6 + 14 = \boxed{8} $
- $ 2h + 15 = 2(3) + 15 = 6 + 15 = \boxed{21} $
- $ h^0 + 12 = (3)^0 + 12 = 1 + 12 = \boxed{13} $
*(Any non-zero number to the power 0 is 1)*

3. Evaluate for y = 10

- $ 4y - 8 = 4(10) - 8 = 40 - 8 = \boxed{32} $
- $ 22 - y^2 = 22 - (10)^2 = 22 - 100 = \boxed{-78} $
- $ y + 10 = 10 + 10 = \boxed{20} $
- $ -y + 25 = -10 + 25 = \boxed{15} $
- $ y - 15 = 10 - 15 = \boxed{-5} $
- $ y^2 - 12 = (10)^2 - 12 = 100 - 12 = \boxed{88} $

---

4. Evaluate for t = -5

- $ 2t + 6 = 2(-5) + 6 = -10 + 6 = \boxed{-4} $
- $ 22 + t^2 = 22 + (-5)^2 = 22 + 25 = \boxed{47} $
- $ t - 10 = -5 - 10 = \boxed{-15} $
- $ -4t + 18 = -4(-5) + 18 = 20 + 18 = \boxed{38} $
- $ 2t - 10 = 2(-5) - 10 = -10 - 10 = \boxed{-20} $
- $ t^3 + 75 = (-5)^3 + 75 = -125 + 75 = \boxed{-50} $

---

5. Evaluate for v = 0.5

- $ v^1 + 4 = 0.5 + 4 = \boxed{4.5} $
- $ 3v + 6 = 3(0.5) + 6 = 1.5 + 6 = \boxed{7.5} $
- $ 12 + v^0 = 12 + (0.5)^0 = 12 + 1 = \boxed{13} $
*(Any non-zero number to the power 0 is 1)*
- $ v + 17 = 0.5 + 17 = \boxed{17.5} $
- $ -2v + 10 = -2(0.5) + 10 = -1 + 10 = \boxed{9} $
- $ v + 5 = 0.5 + 5 = \boxed{5.5} $
