7th Grade Milestone Review - Adding Linear Expressions

Front

What is a linear expression?

Back

A linear expression is an algebraic expression in which each term is either a constant or the product of a constant and a single variable raised to the first power.

Front

How do you combine like terms in an expression?

Back

To combine like terms, add or subtract the coefficients of terms that have the same variable raised to the same power.

Front

What is the result of (x + 9y + 5) – (-8x + 4y – 7)?

Back

9x + 5y + 12

Front

What does it mean to simplify an expression?

Back

To simplify an expression means to combine like terms and reduce it to its simplest form.

Front

What is a coefficient in an algebraic expression?

Back

A coefficient is a numerical factor that multiplies a variable in an algebraic expression.

Front

What is the difference between a term and an expression?

Back

A term is a single mathematical entity (like 3x or -5), while an expression is a combination of terms (like 3x + 2).
