Answer 1

\[\sqrt{w}+5=20\]

Answer 2

Answer 3

Subtract 5 from both sides to get:
15 = sqrt(w)

From there you can take both sides to the second power to get:
w = 15^2
w = 225

Answer 4

Remember to do reverse order of operations when solving these - add/subtract from both sides first, then do your multiplication/division, finally dealing with exponents.

Answer 5

\[\sqrt{w}= 20- 5 \]
\[w = 15^{2}\]
