Question

Maria heard on the radio that the high temperature that day would be 64 degrees Fahrenheit. To determine the temperature in degrees Celsius, she used the formula C = StartFraction 5 Over 9 EndFraction (F minus 32), where C is the temperature in degrees Celsius and F is the temperature in degrees Fahrenheit. Which describes a correct step in the process Maria should take to convert the temperature? Check all that apply.

Substitute 64 for F.
Substitute 64 for C.
Subtract 32 from F before multiplying by StartFraction 5 Over 9 EndFraction.
Multiply the value of F by StartFraction 5 Over 9 EndFraction before subtracting 32.
64 degrees Fahrenheit is approximately 3.6 degrees Celsius.
64 degrees Fahrenheit is approximately 17.8 degrees Celsius.

Answer 1

Substitute 64 for F.

Subtract 32 from F before multiplying by StartFraction 5 Over 9 EndFraction.

64 degrees Fahrenheit is approximately 17.8 degrees Celsius.

Explanation:

uh hi how was your day or night?

Answer 2

Substitute 64 for F.

Subtract 32 from F before multiplying by StartFraction 5 Over 9 EndFraction.

64 degrees Fahrenheit is approximately 17.8 degrees Celsius.

Explanation:

formula for conversion of F to C

C = 5/9(F-32)

C = 5/9(64-32) = 5/9(32) = 17.8 degrees C
