My Scribe:Algebra Test #1

Here are the first set of questions Mr.Harbeck gave us

1. 3x+8 - 3 times plus eight

2. 7x+5x - 7 groups of a number plus 5 groups of a number

3. 5(x+8) - five times the sum of a number and eight

4. 8-3x - 8 decreased 3 times a number

5. 9 centimeters less than three fourths of length X - 3/4x9

6. seven decreased by four times a number - 7-4x

7. 9 less than 3 times a number - 3x-9

8. four more then 8 times a number - 8x4+

On the second part of our test we had to do a graph, tee-chart

and find and algebraic equation for our problem.

Here was our question:

Here Is My Tee-Chart

Here Is My Graph

Now I am to show you how I ended up with these anwers

using my algebraic equation

Let x = Figure #

Let y = Number of Tiles

The Algebraic Equation is.....

3x+1=y

x=figure #

-start with one

-increase by one

y=# of tiles

-start with four

-add three each time

That is my Algebra Test #1 Scribe

Thats practically what we did on the test.
