Answer:
S,Z and W,X
Step-by-step explanation:
If you look at your number line, you will see that point Z (20) is positive and point S (-20) is negative. The opposite of a positive is a negative, which makes -20 and 20 opposites. This goes for -5(W) and 5(X) as well.
-0.05 is larger. Since they're negative, you're going by which is closer to 0 rather than farther. -0.05 is closer to 0 on a number line, so it's larger than -0.25.
