3s+28=85, take away 28 from both sides of the equals to give you 3s=57, divide by 3 on both side to give you s=19.
Hope this helps. :D

Answer:
In x + 2 = 7, x is a variable,
Step-by-step explanation:
Answer:
-1 1/3 as a mixed number (if they ask for it in simplest form, choose this one)
-4/3 as an improper fraction
Step-by-step explanation:

The first thing we are going to do to solve the problem is to define what associative property is:
Associative property Property that is fulfilled if, given any three elements of a given set, it is verified that there is an operation that verifies equality
An expression that meets the definition is:
(x + 3) + 7 = x + (3 + 7)
We observe that both members of equality are identical, but written in different ways.
Answer:
B) (x + 3) + 7 = x + (3 + 7)
