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? a. –6.5 – 3.5 – t = –12 b. –6.5 + 3.5 + t = –12 c. –6.5 + 3.5 – t = –12 d. –6.5 – 3.5 + t = –12
