Translating Equations and Operations

The video tutorial introduces basic riddles involving simple operations and explains how to use hanger models to solve equations. It covers the concept of balancing equations using inverse operations, and explores multiplication and division in equations. The tutorial also demonstrates how to apply division using hanger models, emphasizing the importance of keeping equations balanced.

What does 'one more than a number is three' mean in terms of an equation?

• x * 1 = 3

• x - 1 = 3

• x / 1 = 3

• x + 1 = 3

In a hanger model, what happens if you remove one block from both sides?

• The hanger remains balanced

• The hanger tilts to the left

• The hanger becomes unbalanced

• The hanger tilts to the right

How do you isolate the variable x in the equation x - 1 = 2?

• Multiply both sides by 2

• Add 1 to both sides

• Divide both sides by 2

• Subtract 1 from both sides

What does 'one less than a number is two' translate to in an equation?

• x - 1 = 2

• x + 1 = 2

• x * 1 = 2

• x / 1 = 2

What does 'twice a number is four' mean in terms of an equation?

• 2 + x = 4

• 2 - x = 4

• 2 / x = 4

• 2 * x = 4

In a hanger model, how do you solve for x when you have 2x = 4?

• Add 2 to both sides

• Divide both sides by 2

• Subtract 2 from both sides

• Multiply both sides by 2

What does 'half of a number is three' translate to in an equation?

• x - 2 = 3

• x + 2 = 3

• x / 2 = 3

• x * 2 = 3

In a hanger model, how do you solve for x when you have x / 2 = 3?

• Divide both sides by 2

• Subtract 2 from both sides

• Multiply both sides by 2

• Add 2 to both sides
