Greater than 100 but less than 150
1/4 (8 + 6z + 12)
------------------------------------------------------------
Combine like terms :
------------------------------------------------------------
1/4 (6z + 20)
------------------------------------------------------------
Apply distributive property :
------------------------------------------------------------
1/4(6z) + 1/4(20)
3/2z + 5
------------------------------------------------------------
Answer: 3/2z + 5
------------------------------------------------------------
Yes due to the fact that additive inverse is the oppsite. so she runs up +4 and runs down -4.
