EQ: How do you evaluate algebraic expressions? I Will... Evaluate algebraic expressions..

Simplify the expressions 1. 3X + 6X - X + 4Y 2. 2(X + Y) - 2X 3. X(X + W) + XW - W EQ: How do you evaluate algebraic expressions? I Will... Evaluate algebraic expressions..

READ The difference between a numeric expression and an algebraic expression is that an algebraic expression contains one or more variables. These variables model a changing or unknown number, and the expression may have different values depending on this quantity. Algebraic expressions can be mathematical models for the real-world situations. EQ: How do you evaluate algebraic expressions? I Will... Evaluate algebraic expressions..

Write the algebraic expression that models the word phrase seven fewer than a number t. EQ: How do you evaluate algebraic expressions? I Will... Evaluate algebraic expressions..

Now you try… 1. Write the algebraic expression for the word phrase two times the sum of a and b. 2. Write the algebraic expression for the word phrase the quotient of the difference between 5 and a number n, and 2. EQ: How do you evaluate algebraic expressions? I Will...
