1) an two step equation has two different operations
2) False
3) To solve a two-step inequality, undo the addition or subtraction first, using inverse operations , and then undo the multiplication or division. The inverse operation of addition is subtraction.
4) Use base tens blocks
5) We can use the base tens blocks to model division.

Answer: 6m</h3>
12m can be written as 6m*2
18m^2 can be written as 6m*3m
Both factorizations have '6m' in them, which shows we have a common factor. This is the greatest common factor as we cannot pull anything further out, ie, 2 and 3m have nothing in common other than 1.
''Decreased'' means subtract and ''times'' means multiplication so the algebraic expression should be 15 - 2 * p.
