Chapter 3 : Expressions and Equations

Write 4y + y in simplest form.

= (4 + 1)y or 5y

Solve 5(-9+11)=?

= +10

Evaluate the expression if X= 9 and Y= 3 x + y - 58 =?

= - 46

Solve -2(x - 8)=?

= -2x + 16

Write the expression in simplest form -3 + 7 - 3r - 12

= -6r - 5

Use the Distributive Property to evaluate each expression. (3 + 6)(-8)=?

= -72

-4j - 1 -4j + 6 =?

= -8j + 5

Solve 1/3(x - 6)=?

= 1/3x - 2

Evaluate the expression if Z= 4 5z - 10=?

= 10

Write the expression in simplest form. 2.8y + 2x + 2.2y + 5x + 4x =?

= 11x + 5y

Write the expression in simplest form. 4j x 4 + 2h x 2

= 16j + 4h

Evaluate the expression if D= 8 d/4

= 2

Evaluate the expression if E= 3 and F= 4 ef/4

Rewrite the expression. 4(x + 7)=?

= 4x + 28

Use the Distributive Property to rewrite each expression. 4(x - 6y)=?

= 4x - 24y

Solve. n + 5n =?

= 6n

Define a variable then write each phrase as an algebraic expression. Anna has volunteered 9 more hours than Tricia.

= h + 9 H= hours

Identify the terms,like terms,coefficients,and constants in the expression. 4 + 5y - 6y +y

Terms= 4, 5y, -6y, y Like terms= 5y, -6y, y Coefficients= 5, -6, 1 Constant= 4

Identify the terms,like terms,coefficients,and constants in the expression. n + 4n - 7n - 1

Terms= n, 4n, -7n, -1 Like terms= n, 4n, -7n Coefficients= 4, -7 Constant= -1

What does Distributive Property mean?

The Distributive Property states that to multiply a sum or difference by a number,multiply each term inside the parentheses by the number outside the parentheses.
