Mathematical Concepts and Problem Solving

This video lesson covers the application of linear equations in real-world scenarios. Students will review skills from previous lessons to prepare for a quiz. The lesson includes exercises on translating word problems into equations and solving them, such as determining the number of games played at an arcade, finding consecutive integers, calculating book pages, and solving for a number. The teacher provides step-by-step solutions and encourages independent practice.

What is the first step in using the commutative property to simplify an expression?

• Divide the entire equation by a constant

• Multiply all terms by a common factor

• Rearrange terms to group similar ones

• Add all constants together

How do you determine the number of tickets sold each day if the total number of tickets and the number sold on the first day are known?

• Multiply the first day's sales by the number of days

• Divide the total number of tickets by the number of days

• Add the first day's sales to the total and divide by the number of days

• Subtract the first day's sales from the total and divide by the remaining days

When converting hours to minutes in a problem, what is the conversion factor used?

• 30 minutes per hour

• 45 minutes per hour

• 90 minutes per hour

• 60 minutes per hour

If Shauna skated for twice as long on Tuesday as she did on Monday, and half the total of Monday and Tuesday on Wednesday, how do you express Wednesday's time in terms of Monday's time?

• Half of Monday's time

• Twice Monday's time

• Twice the sum of Monday and Tuesday's time

• Half of the sum of Monday and Tuesday's time

What is the final step in solving for x in a linear equation?

• Subtract the constant from both sides

• Divide both sides by the coefficient of x

• Multiply both sides by a constant

• Add all terms to one side
