Answer: 1. -4<n<4

2. n<-3 or n>19

3. n<=-36 or n>=44

Step-by-step explanation:

n=number

units from a number is measured using absolute value sign

1. 4 units from 0: |n-0|<4 ==> |n|<4

n<4, n>-4 ==> -4<n<4

2. 11 units from 8: |n-8|>11

n-8>11

n-8+8>11+8

n>19

n-8<-11

n-8+8<-11+8

n<-3

n<-3 or n>19

3. half a number is at 2 units from 20:  |n/2-2|>=20

n/2-2>=20

n/2>=22

n>=44

n/2-2<=-20

n/2<=-18

n<=-36

n<=-36 or n>=44
