example: convert 25°c to °f.

formula: °f = (9/5) (°c) + 32  °c is given so i am solving for °f.
°f = (9/5) (25) + 32
=(1.8*25)+ 32
=45+32
=77
answer= 77°f is equal to 25°c

a. convert 35°c to °f

b. convert 80°f to °c

c. convert 15°c to °f

d. convert 25°f to °c

Angel !  You have a formula, and you have an example that's
completely worked out.  The ONLY POSSIBLE reason that you
could still need help is that you're letting math scare you.

I'll do 'A' for you, 'B' most of the way, and get 'C' set up.
If THAT's not enough for you to run with and finish them all,
then you and I should both be embarrassed.

Write the formula on the wall:

                                   °F  =  (9/5) °C  +  32°

A).  Convert 35° C        °F  =  (9/5)(35°) + 32°

(9/5)(35) = 63              °F  =      63°      + 32°

                                     °F  =  95°


B).  Convert 80°F to °C 
                         The formula:    °F  =  (9/5) °C  +  32°

°F = 80                                     80  =  (9/5)°C  +  32

Subtract 32 from each side:      48 = (9/5)°C

Multiply each side by  5 :        240  =  (9) C

Now you take over:


C).  Convert 15°C to °F.
                         The formula:    °F  =  (9/5) °C  +  32°

°C = 15                                      °F = (9/5) 15° + 32

(9/5) (15) = 27     
                             Go !              °F  =
