Example 1.153 from Elementary Algebra, 1.10 Systems of Measurement

Systems of Measurement: example 1.153

Convert $50 °$ Fahrenheit into degrees Celsius.

Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.

Solution
We will substitute $50 ° F$ into the formula to find C.

Simplify in parentheses.

Multiply.

So we found that 50°F is equivalent to 10°C.

Your turn

The book's Try It right after this example: same idea, new numbers. Only the answer is given.

Convert the Fahrenheit temperature to degrees Celsius: $59 °$ Fahrenheit.

How did it go?
