1.Ms. Enigma said, “Five less let x = Ms. Enigma’s age.
than one third of my age is
14 is my age” How old is Ms.
Enigma?

The first thing that we do is make a sentence answer…..

Ms. Enigma is ______________ years old.
1/3x - 5= 14
To get ride of our integer we have 5to do some
Opposite operations.
1/3x – 5 = 14
1/3x +5 = 14

Now what we do to one side we do to the other.
14 + 5 = 19
x/3 is the same as saying 1/3
x/3 = 3(19)
3 times 19 = x = 57 Ms. Enigma is 57 years old
Our last step is to substitute to check

1/3x – 5 = 14
57/3 – 5 = 14
14 = 14

2.Suppose you have 5o dollars let x = the number of hours
And earn 8 dollars per hour. You must work
How many hours must you
Work until you have 170 dollars?
Now we make a one sentence answer……

You must work _______________ hours.
Hour 1= x _____________ = x = 15

Dollars per hour = 8x____ = 8(15) =
TOTAL= 8x + 50 170 dollars
- 50 ___-50___________
------------
X= 15 8x = x 120
_____ _____ = 15 h
8 8
The last step is to substitute to check

8x + 50 = 170 dollars
8(15) + 50 = 170 dollars 170 = 170

SORRY GUYS I WILL GHET THE REST UP TOMORROW:(:(:(:(:(

Equation Solving --- Multiplying and Dividing ---

Steps to success...

1. Isolate the variable
2. Cancel the variable
Using its opposite x or /
to get 1 variable


2a.) - negative variables must be cancelled by - variables to create a positive variable
3. Balance
4. Substitute to check

Jordan's Pattern Investigation 2 Scribe

Car Repairs


2. Make a Table to Show the results of Your Investigation
3. Describe The Patterns Found In Each Row
Figure # - Start With 1, Increase by 1
# Of Repairs - Start With 1, Increase by 2

B. Describe Why The Patterns Increase The Way That They Do.
With every figure # your car needs two more repairs.

4. Describe The Relationship Between The Two Columns
Multiply figure # by 2 then subtract 1.

C. Write An Algebraic Equation To Show This Relationship
Let X represent Figure # = 2X-1

5. Predict What The 20th, 35th and 99th digram will look like

20th - 2X-1 2x20-1 40-1 = 39
35th - 2X-1 2x35-1 70-1 =69
99th - 2X-1 2x99-1 198-1 =197
