2) Simplify: 5(x + 3) - 2(x + 4)
3) Find 1/2mv2, when m = 8 and v = 2
4) In a bag of 60 marbles, 18 are green. What is the
probability of NOT drawing a green one?
5) Annie has answered 21 of the 25 questions. What percent
of the questions has she answered?

3. Lesson 50:
FYI - REMEMBER...to solve equations we must:
"ISOLATE THE VARIABLE"
So...sometimes we must do multi-step equations....
HOWEVER, we must "undo" the adding/subtracting...
BEFORE we "undo" the multiplying/dividing.
(opposite of Order of Operations)
AND...sometimes we have to "combine like terms" before doing
any steps to solve it!!
