At 4pm the temperature started to change drastically each hour for 3 hours the temperature decreased by 7°F wich expression best shows another way to write the product for the temperature change

(-1)(7+7+7)

Step-by-step explanation:

given data

change drastically each hour =  3 hour

temperature decreased = 7°F

solution

we get some option that are

7+7+7

7+7+7+7

(-1)(7+7+7)

(-7)+(-7)+(-7)+(-7)

First, as the temperature decreases, it means that the final answer is negative, or that the change must be multiplied by -1. The temperature varies from 7. to every hour. There is also the question of whether the temperature changes for 3 hours. Hence the temperature change is from 3 7, or 7 + 7 + 7. In the last we add -1 from the beginning because this is a negative temperature change, the answer is (-1) (7 + 7 + 7)

If gravity is one third on mars then weight also one third on mars
