Step-by-step explanation:

Given that :

Dimension of poster board = 1 yd by 1 yd

Dimension of each poster sign = 1/3 yd by 1/9 yd

Answer:

I don't know if this what you want but I will explain how I think the answer is.

Step-by-step explanation:

a) You're at positive 5, and the integer explains that you're adding negative three spaces, which just means you go back three spaces. Your spot on the number line should be 2.

b) It says to go 3 spaces back from 5. Your spot on the number line will be two.

c) You're at negative 3, and you go another 5 spaces back. Your spot on the number line will be -8.

d) You're on -3 on the number line. You remove positive 5, so your new spot on the line is -8.

e) You're at -5. You're removing positive 3. Your going back three spaces. So you would be at -8.
