Common Core Algebra I
The full experience and value of eMATHinstruction courses are achieved when units and lessons are followed in order. Students learn skills in earlier units that they will then build upon later in the course. Lessons can be used in isolation but are most effective when used in conjunction with the other lessons in this course. All Lesson/Homework files, Spanish translations of those files, and videos are available for free. Other resources, such as answer keys and more, are accessible with a paid membership .
If you have an Algebra I membership, please note that you also have access to the paid resources for N-Gen Math Algebra I.

Math With Mrs. Molina
There are two things we must give children: the first one is roots and the other wings., unit 3: equations and inequalities, click here to go to the ixl website for all kinds of 8th grade topics and review problems..
What is an equation?
Examples: 4 + 3 = 7 or 3x + 5 = 10
An equation is a number sentence. We call it an equation because it has an equal sign.
The 5 Steps to Writing an Equation or Inequality
Step 1. read and underline the question, step 2. find your χ (your variable/unknown) and box it, step 3. circle the math words (product, quotient, each, per, together, sum, difference, squared ), step 4 . replace the operation words with their symbols ( • , + , – , ÷ , / , = , < , > , ≤ , ≥ ,√ , ≠ , ² , ³ ), step 5. write the equations.
Don’t forget our cool ‘dance’ we did to remember this!

With Equations, Inequalities and Expressions we always want to combine like terms 1st!
Here is an example on how to do that:
Once all like terms have been combined then we can solve.

Solving Equations Algebraically
Here is another example solving algebraically, solve √(x/2) = 3.
| Start With | √(x/2) = 3 | |
| Square both sides: | x/2 = 3 | |
| 3 = 9: | x/2 = 9 | |
| Multiply both sides by 2: | x = 18 |
And the more “tricks” and techniques you learn the better you will get.
Here is an example of how we solved equations in class:

Systems of Equations
For information on systems of equations click here ., simple vs. compound interest, introduction to interest :.
http://www.mathsisfun.com/money/interest.html
SIMPLE INTEREST
I = Prt
- I = interest owed [$] (this is ONLY the interest borrowed)
- P = amount borrowed (called “Principal”) [$]
- r = interest rate [%] (you have to divide the percent by 100) For information On Percents click here !
- t = time [years]
Simple interest is money you can earn by investing some money (the principal). The interest (percent) is the rate that makes the money grow!
COMPOUND INTEREST
A = P(1+r)^t
- A = All of it / Actual / total amount owed (this amount includes the interest and the principal) [$]
- P = amount borrowed (called “Principal”) [$]
- r = interest rate [%]
Compound interest is very similar to simple interest. The difference is that compound interest grows much faster ! The reason it grows faster is because the interest (percent) has an exponent .
********** MAKE SURE TO READ THE QUESTION AND SEE EXACTLY WHAT IT IS ASKING DOES IT JUST WANT THE INTEREST OR THE TOTAL (All of it) ???????? *************************

A = (pi)r^2. The area A of a circle is pi times the radius r squared. P = a + b + c. The perimeter P of a triangle is equal to the sum of the side lengths of a, b, and c. V = lwh. The volume V of a rectangular prism equals the product of the length l, the width w, and the height h. 3 (d + 4) = 32.
If you solve an equation and your solution is a variable equal to a number, you have ONE solution. EX: x = -3 If you salve an inequality, be careful of what actually is a solution. It must make the inequality statement TRUE. EX: x < 4 the number 4 NOT a solution because 4 is not less than 4 but 3, 2, 1, -50, etc. are all solutions.
