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.
