Math help! Find a Temperature in either Fahrenheit or Celsius?

I need to answer 4 math questions using the formulas:





F= 9/5C + 32 or C= 5/9 (F - 32)





1.) What is the temperature in degrees Fahrenehit when it is


0° C?





2.) What is the Temperature in degrees Fahrenheit when it is


100°C?





3.) What is the temperature in degrees Celsiui when it is


- 4°F?





4. What is the temperature in degrees Celsius when it is


77°F?





Any help would be appreciated. I have no idea how to use those formulas. Thanks

F= 9/5C + 32


1.) What is the temperature in degrees Fahrenehit when it is


0° C?





you substitute C =0 into the equation


F = 9/5(0) +32 = 0 +32 =32 F





****************************


2.) What is the Temperature in degrees Fahrenheit when it is


100°C?


you substitute C =100 into the equation


F =9/5(100) +32 = 900/5 +32 =180 +32 =212 degrees F


***************************


3.) What is the temperature in degrees Celsius when it is


- 4°F?


you substitute F = -4 into the equation


C= 5/9 (F - 32) to get


C = 5/9(-4 -32) =5/9(-36) = -(5/9)(36) = -20 C





***********************************


4. What is the temperature in degrees Celsius when it is


77°F?


you substitute F = 77 into the equation


C= 5/9 (F - 32) to get


C = 5/9(77 -32) = 5/9(45) = 25 C





Good luck!
Reply:You just sub in the value that is given to solve for what ever it is that you are looking for....








1) F = 9/5(C+32) = 9/5(0+32) = 57.6





2) F = 9/5(100+32) = 9/5(132) = 237.6





3) C = 5/9(F-32) = 5/9((-4)-32) = 5/9 (-36) = -20





4) C = same as #3 just subbing in different #s ---- = 22.8
