Question

1. match the correct equation to the question it would answer.

draggable item → corresponding item
the temperature dropped 15 degrees over 5 hours. how much did it change each hour? → b = (-15)(5)
the temperature was 15 degrees and dropped to -5 degrees. how much did the temperature change? → b = -5 - 15
the temperature dropped 15 degrees each hour for 5 hours. how much did the temperature change in total? → b = -15/5

Explanation:

Step1: Match hourly drop question

To find the hourly temperature change, divide total drop by hours: $b = \frac{-15}{5}$

Step2: Match total change from 15 to -5

To find total temperature change, subtract initial from final: $b = -5 - 15$

Step3: Match total drop over 5 hours

To find total temperature change, multiply hourly drop by hours: $b = (-15)(5)$

Answer:

1. The temperature dropped 15 degrees over 5 hours. How much did it change each hour? → $b = \frac{-15}{5}$
2. The temperature was 15 degrees and dropped to -5 degrees. How much did the temperature change? → $b = -5 - 15$
3. The temperature dropped 15 degrees each hour for 5 hours. How much did the temperature change in total? → $b = (-15)(5)$
