Answer:
A) ![T=\frac{-20}{4}](https://tex.z-dn.net/?f=T%3D%5Cfrac%7B-20%7D%7B4%7D)
B) T = -5 °C
Step-by-step explanation:
A) Let T be the change in temperature of the week. T is determined as the total temperature change (-20°C) divided by the number of weeks that have passed (4 weeks). The expression is:
![T=\frac{-20}{4}](https://tex.z-dn.net/?f=T%3D%5Cfrac%7B-20%7D%7B4%7D)
B) In order to simplify the expression, simply perform the division.
![T=\frac{-20}{4}\\T=-5^oC](https://tex.z-dn.net/?f=T%3D%5Cfrac%7B-20%7D%7B4%7D%5C%5CT%3D-5%5EoC)
This means that the temperature has dropped by 5 degrees each week.
