PART 2-PA First Semester Review-December 2024

Front

What are like terms in an expression?

Back

Like terms are terms that have the same variable raised to the same power. For example, 3x and -9x are like terms because they both contain the variable x.

Front

Combine the like terms: 3x + 7 - 9x + 24y + 2x²

Back

-6x + 7 + 24y + 2x²

Front

What is the first step to solve the equation: 11 - 3x = 44?

Back

Subtract 11 from both sides.

Front

Solve the equation: 5x + 34 = -2(-7x + 1)

Back

x = 4

Front

For the equation ___ + 12 = -4x + 12 to have infinite solutions, what must go in the blank?

Back

-4x

Front

What is the result of combining like terms: n - 10 + 9n - 3?

Back

10n - 13

Front

What does it mean for an equation to have infinite solutions?

Back

An equation has infinite solutions when any value of the variable satisfies the equation, meaning both sides are equivalent for all values.

Front

What is the definition of a variable in mathematics?

Back

A variable is a symbol, often a letter, that represents an unknown value in an expression or equation.

Front

What is the process of solving an equation?

Back

The process of solving an equation involves isolating the variable on one side of the equation to find its value.

Front

What does it mean to combine like terms?

Back

Combining like terms means to simplify an expression by adding or subtracting terms that have the same variable and exponent.
