Distributive Property

Hello everybody I am back here again with the Distributive Property!!!!!! Today we'll review more about this totally important property to Algebra...

Well, first the distributive property is a property used to solve a(b+c), before, you would usually solve for b+c, and then multiply by a, but with the distributive property, you would DISTRIBUTE the a for both b and c, and then solve it.

So that is the basic thing, but lets go to the example,

Ex.:     2(1+3)

     2×1 + 2×3

         2 + 6

            8

Now it's time to practice...

1. 4(3 + 5)

2. 5(7 - 4)

3. 3(x + y)

4. The Rosa family recently dined at an Japanese restaurant. Each of the four family members ordered a sushi combo that costs $20, tea that cost $2, and dessert that cost $3. What was the cost of dinning out for the Rosa family?

5. 4(6v + 2s - 2v)

Answers:

1. 32

2. 15

3. 3x + 3y

4. The equation used should be : 4(20 + 2 + 3), where 4 is the family members in which each ate the sushi combo + tea + dessert, 20 should be the sushi combo's price, 2 should be the tea's price, and 3 should be the dessert's price, everything's result is 100.

5. 16v + 8s

Thank you for the visit, and see you soon with our next topic in which is Relations, bye!

Introduction

Hello everybody, how are you? This is my first post in this blog of review on Algebra, that is going to help you with any question you are struggling to understand. Basically I am going to post notes about a subject, explain it with examples and then, I'll give you a few problems with answers right below it.


This is going to be the layout of the blog...


Notes:
-Intro
-Explanation/Properties
-Examples


The problems are going to be five:
1 - an easy one to get what we've just learned;
2 - to fix some properties learned;
3 - to make sure you got it;
4 - a writing problem;
5 - the challenge.


And right below the problems, there are going to be the answers...


Well... This was today's post, explaining the blog's layout, but tomorrow I am back with my first subject which is the Distributive Property... See you soon, bye!
