 EQUATIONS

slide 2 objective

Objective Is for us to create a Google  Presentation to demonstrate conceptual knowledge of writing and solving equations, and we’ll use knowledge we have gained from the first 9 week period.We will also use the real numbers property, and the properties of equality.

Definition for equation = a statement that values of two mathematical expressions are equal indicated by equal sign =.

slide 3 demanstration

                            4x=⅖

                                                     ¼ x 4/1 x = ⅖ x ¼

                                              x = 2/20

                                             x=10

You have 4 so you would put one under the four so it looks like this 4/1. Then multiply it by ¼ which is the multiplicative inverse, and you have to do it to the other side too.

slide 4 demanstration

x-¼=⅖   

x-5/20 = 8/20   Get a common denominator

+5/20   +5/20 8/20 + 5/20 = 13/20

x=13/20 The addition property of equality is shown by add 5/20 to both sides.

Slide 5 demanstration

15-⅔  x=20

-⅔ x=5        -3/2 x -⅔ x=5/1 x 3/2 = 15/2  

x=-7.5

You used subtraction property of equality by subtracting 15 from both sides. You used multiplicative inverse by multiplying -⅔ times -3/2. Then you do it to the other side to multiplying 5/1x-3/2.

slide 6 demanstration

5-2(x-3)=-23

5-2x+6=-23

       -6    -6        5-2x=-29        

                           -5     -5        -2x divided by -34

x=17           You used distributive property by multiplying -2 x x and -2 x -3. Division property of equality is show by -2x divided by -2 and -2 divided by -34

Example Slide 7

Prince Fielder has hit 20 home runs and he hits 2 every game. Josh Hamilton hit 25 home runs he hits 1 every game. In how many games will they have the same amount of homeruns?

Slide 8 answer for slide 7

20+2x=25+1x

     -1x     -1x

20+1x=25

-20      -20

1x=5

x=5

You used subtraction property of equality by subtracting 20 from both sides.

I Miss 2013 and Welcome 2014

2013 just came to an end and I want to tell you about it. This year my family got a swimming pool. It is a salt water pool and is 13 feet with a cave.When the workers were done with the digging I thought it was 18 feet deep. It took 2 moths to finish the pool. The outside of it had a fir place, a grill,and a walk in into the pool. My dad, brother,and I went deep sea fishing in Seattle. When we went we got up at 4:30 and went and met our guide. Then we went fishing and we caught 32 flounder they are a flat fish that lives at the bottom of the ocean. This year I want to pass the star test. I want to shoot my first pig. I want to stop chewing on my fingers. I want to learn how to clean fish. I want to read Dairy of a wimpy kid, Old yeller, Hunger Games, and Jackie and Me.
