Solving One-Step Inequalities

The video tutorial introduces the concept of inequalities, explaining their characteristics and how they differ from equations. It covers solving one-step inequalities using examples and practice problems. The lesson concludes with a summary and credits to contributors.

What does the prefix 'in' in 'inequality' imply about its meaning?

• Infinite

• Not equal

• Inside

• Integral

Which sign represents 'less than or equal to'?

• >=

• <=

• >

• <

How do you solve the inequality 4x > 12?

• Subtract 12 from both sides

• Add 12 to both sides

• Divide both sides by 4

• Multiply both sides by 4

What is a possible solution for x in the inequality 5 + x < 30?

• 30

• 35

• 25

• 40

How is solving inequalities similar to solving equations?

• They use the same mathematical operations

• They always use the greater than sign

• They both have only one solution

• They cannot have negative solutions

Why are equations not considered as inequalities?

• They use different signs

• They represent quantities that are equal

• They represent quantities that are not equal

• They have multiple solutions

What is a non-example of an inequality?

• x = 9

• x > 10

• x <= 7

• x < 5

In real-life scenarios, when can inequalities be used?

• To calculate the sum of two numbers

• To determine exact quantities

• To specify conditions that have a range of solutions

• To find the difference between two numbers

What does it mean if an inequality sign is underlined?

• The inequality is invalid

• The values are exactly equal

• The values are not equal

• The value can be equal or less/greater than

Why is practice important when learning to solve inequalities?

• To understand the concept of equality

• To learn how to use a calculator

• To memorize the inequality signs

• To improve problem-solving skills
