Examples, worksheets, videos and solutions to help Grade 8 students learn a real-world application of linear equations with respect to the conversion of temperatures from Celsius to Fahrenheit and Fahrenheit to Celsius.

Lesson 30 Student Outcomes

• Students learn a real-world application of linear equations with respect to the conversion of temperatures from Celsius to Fahrenheit and Fahrenheit to Celsius.

Lesson 30 Student Summary

• We know how to use a linear equation in a real-world situation like converting between Celsius and Fahrenheit.

• We can use the computations we make for specific numbers to help us determine a general linear equation for a situation.

Lesson 30 Classwork

Our goal is to address the following two questions:

(1) If t is a number, what is the degree in Fahrenheit that corresponds to t°C?

(2) If t is a number, what is the degree in Fahrenheit that corresponds to (-t)°C?

What is 37°C in Fahrenheit? Explain.

Exercises
