Equation Story Problem Flashcard

Front

What is a pan balance?

Back

A pan balance is a device used to compare the weight of two objects. It has two pans suspended from a beam, and when the weights are equal, the beam is level.

Front

What does it mean to balance a pan balance?

Back

To balance a pan balance means to have equal weights on both sides so that the beam remains horizontal.

If Kevin has 10 cubes on the right and 4 on the left, how many cubes does he need to add to the left to balance after doubling the right?

Back

He needs to add 16 cubes to the left side.

Front

What is a multi-step equation?

Back

A multi-step equation is an equation that requires more than one step to solve, often involving operations like addition, subtraction, multiplication, or division.

Front

How do you solve for p in the equation 5 + p + 7 = 5 + 6 + 5?

Back

Combine like terms to find p = 4.

Front

What is the total weight on the right side if Brandy places weights of 1g, 5g, and 10g?

Back

The total weight is 16 grams.

Front

What combination of weights cannot balance the pan if Brandy has 2g and 4g weights?

Back

Three 4-gram weights and one 2-gram weight cannot balance.

Front

If Will has 12 cubes on the right and adds 14 to the left, how many does he need to add to the right to balance?

Back

He needs to add 5 cubes to the right side.

Front

What is the purpose of using tools in balancing problems?

Back

Tools help visualize and calculate the necessary weights or cubes needed to achieve balance.

Front

What does it mean to add more cubes to one side of a balance?

Back

Adding more cubes to one side increases its weight, which may help achieve balance if the other side is lighter.
