PART A
The hottest temperature ever recorded in a certain state was 123° F
The lowest temperature in the state's history was recorded -55° F.
Therefore the subtraction statement between the temperatures is 123F-(-55)F
[tex]\begin{gathered} 123-(-55) \\ =123+55 \\ =178^0F \end{gathered}[/tex]Therefore the difference in temperature is 178F
PART B
Since the temperature -1° F rose by 18° F, this gives an addition statement.
-1F+18F
[tex]\begin{gathered} -1+18 \\ =17^0F \end{gathered}[/tex]Therefore the new temperature is 17F
PART C
Since the temperature went down from 44° F to -8°F. This gives a subtraction statement.
44F-(-8)F
[tex]\begin{gathered} 44F-\mleft(-8\mright)F \\ =52F \end{gathered}[/tex]The temperature fell by 52F
PART D
Brooke's house had a temperature of 51°F. she put the heat on and the temperature rose by 15° F.
This part leads to an increase in the temperature.
[tex]51F+15F=66F[/tex]Also, as she was still cold, Brooke lit a fire and that increased the temperature by 10°F.
This part also leads to an increase in temperature.
[tex]\begin{gathered} 66^0F+10^0F \\ =76^0F \end{gathered}[/tex]The new temperature in the house is 76F
