The temperature at 7:00 a.m, was 12 C, and by 7:00 p.m, it had dropped

to -10°C. Which expression represents the change in temperature:

(A 12 + (-10)

(B 12 - 10

(C -10 + 12

(D -10 - 12

Answer 1

Answer: D -10 - 12

Explanation:

Temperature change is (Final T) - (Initial T)

(Final T) = -10C

(Initial T) = 12

(Final T) - (Initial T) = -10C - 12C

Temp Change - 22C
