Balance Equations Hangers

Front

What is a balanced equation?

Back

A balanced equation is an equation in which the number of atoms for each element is the same on both sides of the equation, ensuring that mass is conserved.

Front

What does it mean to isolate a variable in an equation?

Back

Isolating a variable means rearranging the equation so that the variable is on one side by itself, making it easier to solve for that variable.

Front

What is the principle of maintaining balance in equations?

Back

The principle states that whatever operation is performed on one side of the equation must also be performed on the other side to maintain equality.

Front

How do you remove terms from both sides of an equation?

Back

You can remove terms by performing the same operation (addition or subtraction) on both sides of the equation.

Front

What is the purpose of using a balance model in equations?

Back

A balance model visually represents equations, helping to understand how to maintain equality by showing how different terms can be added or removed.

Front

What is the value of 'b' if 3 + b = 21?

Back

b = 18 (subtract 3 from both sides).

Front

How do you solve for 'h' in the equation h + 20 = 50?

Back

Subtract 20 from both sides to isolate h: h = 30.

Front

What is the first step in solving the equation 2x + 5 = 15?

Back

Subtract 5 from both sides to get 2x = 10.

Front

What does it mean to perform the same operation on both sides of an equation?

Back

It means applying the same mathematical operation (addition, subtraction, multiplication, or division) to both sides to keep the equation balanced.

Front

If you have 4 circles on one side of a balance, how many circles can you remove to keep it balanced?

Back

You can remove 4 circles from both sides to keep the balance.
