Question

1. the table shows temperatures in an arctic city during one winter week. a complete the table.

Explanation:

Step1: Calculate Tuesday's noon temperature

To find the temperature at noon, add the temperature change to the midnight - temperature. So, $-17.5 + 17.5=0$.

Step2: Calculate Wednesday's midnight temperature

Let the midnight temperature be $x$. We know that $x + 15.5=10.5$. So, $x=10.5 - 15.5=-5$.

Step3: Calculate Thursday's temperature change

Let the temperature change be $y$. We know that $-12.2 + y=-24$. So, $y=-24+12.2=-11.8$.

Step4: Calculate Friday's noon temperature

Add the temperature change to the midnight - temperature. So, $-21.8 + 17.3=-4.5$.

Answer:

	Temperature at Midnight ($^{\circ}$F)	Temperature Change From Midnight to Noon ($^{\circ}$F)	Temperature at Noon ($^{\circ}$F)
Tuesday	-17.5	+17.5	0
Wednesday	-5	+15.5	10.5
Thursday	-12.2	-11.8	-24
Friday	-21.8	+17.3	-4.5
