Question

The temperature at noon was –6.5⁰C. The temperature rose 3.5⁰C from noon to 1 p.m. The temperature decreased t degrees centigrade from 1 p.m. to 2 p.m. The temperature at 2 p.m. was –12⁰C.

Which equation can be used to solve for t?

anonymous · Answer

[-12 - (a + b)] = t
a = temperature at noon
b = temperature at one PM
I didn't check this to see if it's right, so, try it out :P
