Final answer:
b. F = 9/5C + 32. The equivalent algebraic expression for the formula used to convert between degrees Fahrenheit and degrees Celsius is F = 9/5C + 32.
Step-by-step explanation:
The formula used to convert between degrees Fahrenheit and degrees Celsius is "the sum of 32 and 9/5 times the temperature in degrees Celsius." To represent the degrees Celsius in algebraic expression, we use the variable C. Therefore, the equivalent algebraic expression for the formula is F = 9/5C + 32.
