A cold front moved in last weekend.The average temperature change for each hour is 4.14 degrees per hour.
Solution:
Given that a cold front moved in last weekend. In 7 hours overnight, the temperate outside dropped 29 degrees
We have to find the average temperature change for each hour.
Average temperature change for 1 hour can be found out by dividing the temperature change for 7 hours (which is 29 degree) by 7 hours.
To compute the average, we need to divide the difference by the time needed, hence we get
Average temperature change for each hour =![\frac{\text {temperature change for } 7 \text { hours }}{7}](/tpl/images/0309/7831/00978.png)
So, the average temperature dropping is 4.14 degrees per hour.

The true options are:
-The inequality should be written as 2.50c less than or equal to 500.
-The circle is closed
-The arrow points right
Hope this helps!! :)
