Solving Multi-step Inequalities and Word Problems

Mrs. Verma Lee presents a video tutorial on solving multi-step inequalities, including a word problem. The video covers three inequality problems and a word problem about budgeting for fair rides. Each problem is solved step-by-step, emphasizing the importance of order of operations and checking solutions. The tutorial aims to help students understand and apply mathematical concepts to real-world scenarios.

What is the main purpose of learning math according to the video?

• To pass exams

• To solve real-world problems

• To memorize formulas

• To impress others

In the inequality X/2 + 3 > 9, what is the first step to isolate X?

• Multiply both sides by 2

• Subtract 3 from both sides

• Divide both sides by 2

• Add 3 to both sides

After isolating X in the inequality X/2 + 3 > 9, what is the next step?

• Subtract 3 from both sides

• Add 3 to both sides

• Divide both sides by 2

• Multiply both sides by 2

When graphing the solution to X/2 + 3 > 9, what type of circle is used at 12?

• Closed circle

• Open circle

• No circle

• Half-filled circle

In the inequality (X - 4)/5 >= 2, what is the first step to isolate X?

• Divide both sides by 5

• Multiply both sides by 5

• Subtract 4 from both sides

• Add 4 to both sides

After multiplying both sides by 5 in the inequality (X - 4)/5 >= 2, what is the next step?

• Divide both sides by 5

• Multiply both sides by 5

• Subtract 4 from both sides

• Add 4 to both sides

What is the importance of checking your work according to the video?

• It helps you memorize the steps

• It ensures accuracy and catches small mistakes

• It impresses the teacher

• It saves time
