Understanding Mathematical Terms and Variables

Mr. Holcomb presents lesson 31, focusing on understanding independent and dependent variables through practical examples. The lesson covers scenarios like reading minutes, website design, movie streaming costs, and exercises involving pencils, books, miniature golf, and school supplies. Students learn to identify variables and create equations to model real-world situations.

In the reading example, what does the variable 'D' represent?

• Total number of pages read

• Total number of minutes read

• Number of days Marcus reads

• Number of books read

In the reading example, which variable is dependent?

• The number of books

• T, the total minutes read

• D, the number of days

• The number of pages

In the website design example, what is the independent variable?

• Number of hours worked

• Number of weeks worked

• Number of websites designed

• Number of clients

What equation represents the number of websites Akira can design?

• D = 3W

• W = 3D

• D = W + 3

• W = D + 3

In the movie streaming example, what is the monthly fee?

• $15.00

• $10.00

• $5.00

• $1.50

What is the cost equation for streaming movies?

• C = $1.50M + $5

• C = $5M + $1.50

• C = $1.50 + $5M

• C = $5 + $1.50M

In the pencils example, what does the variable 'P' represent?

• Number of erasers

• Number of pens

• Number of packages

• Total number of pencils

In the books example, what is the dependent variable?

• Number of chapters

• Number of pages

• Number of weeks

• Number of books read

In the school supplies example, what is the cost of each notebook?

• $1

• $2

• $3

• $4

What is the equation for the total cost of school supplies?

• T = 5N + 3

• T = 2N + 3

• T = 3N + 2

• T = N + 5
