Question

Ken predicts that the average temperature will be −5°C in December. If he predicts the temperature will rise 6°C in January and fall 3°C in February, which of the following equations can he use to find the sum of the temperatures for those months? Check all that apply. [6 + 3] + 5 = 14 (–5) + [3 + 6] = –4 [(–5) + (–3)] + 6 = –2 5 + [(–6) + (–3)] = –4 [6 + (–5)] + (–3) = –2 [(–5) + 6 ] + (–3) = 4

Answer 1

C E

Explanation:

Answer 2

The equations [(-5) + (-3)] + 6 = -2 and [6 + (-5)] + (-3) = -2 he can use to find the sum of the temperatures for those months ⇒ 3rd , 5th
