Equations and Expressions Flashcard

Front

What is the value of h in the equation \(\frac{2}{5} h = 2\)?

Back

5

Front

How do you solve the equation \(4 - 2x = 10\)?

Back

Subtract 4 from both sides to get \(-2x = 6\), then divide by -2 to find \(x = -3\).

Front

What is the simplified form of the expression \(2(3x - 4) + 5x\)?

Back

The simplified form is \(11x - 8\).

Front

What equation corresponds to the model \(2x + 4 = 10\)?

Back

The equation is \(2x + 4 = 10\).

Front

How do you find the value of x in the equation \(2(x + 4) = 16\)?

Back

Divide both sides by 2 to get \(x + 4 = 8\), then subtract 4 to find \(x = 4\).

Front

What is an equation?

Back

An equation is a mathematical statement that asserts the equality of two expressions.

Front

What is an expression?

Back

An expression is a combination of numbers, variables, and operators without an equality sign.

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 are like terms?

Back

Like terms are terms that have the same variable raised to the same power.

Front

What is the distributive property?

Back

The distributive property states that \(a(b + c) = ab + ac\).
