Step-by-step explanation:
LEts analyze the given number line
We always start with 0
Arrow goes 3 units to the right, so we put positive 3
from 3 , the arrow ends at -2.5. Arrow goes to the left so we subtract to find the distance. -2.5-3= -5.5
from -2.5 we add 1.5 to reach -1
So the expressio becoems 3 and then subtract 5.5 and then add 1.5
3 - 5.5 +1.5
