Use the formula upper f equals nine fifths upper c plus 32 to convert negative 25 degrees c to degrees fahrenheit. what formula gives the conversion from degrees fahrenheit to degrees celsius?
a. c=f-32-(5/9)
b. c=(5/9)(f-32)
c. c=(9/5)(f+32)
d. c=(9/5)(f-32)

B.  

Step-by-step explanation:

The given formula :

To convert this formula in terms of C , we first Subtract 32 on both sides , we get

Now multiply 5 on both the sides , we get

Divide both sides by 9 we get

OR

Therefore , the formula gives the conversion from degrees Fahrenheit to degrees Celsius will be :-

Hence, the correct answer : B.  

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )
