What are like terms?

Back

Like terms are terms that have the same variable raised to the same power. For example, 2x and 3x are like terms, while 2x and 3y are not.

How do you simplify the expression 2x + 1 + 7x?

Back

Combine like terms: 2x + 7x = 9x, so the simplified expression is 9x + 1.

Front

What is the result of the expression 2(x + 4)?

Back

Distribute the 2: 2 * x + 2 * 4 = 2x + 8.

Front

How do you solve the equation -12 - 6x = -60?

Back

Add 12 to both sides: -6x = -48. Then divide by -6: x = 8.

Front

When do you use a closed dot on a graph of an inequality?

Back

You use a closed dot when the inequality includes 'less than or equal to (≤)' or 'greater than or equal to (≥)'.

Front

What is the difference between an equation and an inequality?

Back

An equation states that two expressions are equal, while an inequality shows the relationship between expressions that are not necessarily equal.

Front

What does it mean to distribute in algebra?

Back

To distribute means to multiply a term by each term inside a parenthesis. For example, in 3(x + 2), you would calculate 3*x + 3*2.

Front

What are the steps to solve a one-variable equation?

Back

1. Simplify both sides if necessary. 2. Use inverse operations to isolate the variable. 3. Solve for the variable.

Front

What is a variable in algebra?

Back

A variable is a symbol, often a letter, that represents an unknown value in mathematical expressions or equations.

Front

What is the purpose of combining like terms?

Back

Combining like terms simplifies expressions, making them easier to work with and understand.
