  Variables: is the unknown or the quantity represented by any letter. Examples: 5y+3; the letter y is the variable example: 9c; the letter c is the variable example: 2x-8; x is the variable Numerical Coefficient: the number along with the variable. It is what you multiply a variable by. example: 3y+7; the numerical coefficient is 3y is 3. example: 8c; the numerical coefficient of 8c is 8. example: 5+3m; the numerical coefficient of 3m is 3. Constant: is a number that does not change.. Example: 5+3m; 5 is the constant , it's a number by itself therefore this number never changes. Example: 4x-3; 3 is the constant term, it's a number by itself therefore it never changes. Example: 7n-5; 5 is the constant term, it's a number by itself therefore it never changes. Loading…

 Directions: Identify which is an expression or an equation and explain how you know. Remember that an expression is a mix of numbers/variables, operations such as adding, subtracting, multiplying, and dividing, without an equal sign. ex. 9y A equation has 2 expressions separated by a equal sign, and each expression has the same value as the other; ex. 5 + 3m=11. 1. 4w=48___________________________________________________________________________ 2. g-11____________________________________________________________________________ 3. 3d+5____________________________________________________________________________ 4. x/12=8__________________________________________________________________________ 5. j-5/10___________________________________________________________________________ 6. 6z+1=67________________________________________________________________________ ( If you forget how to solve, review back on the video of expressions and equations).

 An imperative sentence expresses a command or request. It is followed by a period (.). Example: Close the door.  An exclamatory sentence expresses strong emotion. It can also express a command or request that is made with great excitement. It is followed by an  exclamation mark (!). Examples:   How you frightened me! Look at that accident! Loading…

Declarative and Interrogative Sentences: A sentence that makes a statement is called a declarative sentence. Example: We have two dogs. A sentence that asks a question is called an interrogative sentence . Example: Do you have a dog? Loading… >
