Respuesta :

The difference is 18.7 degrees

Answer:

18.7∘

Step-by-step explanation:

The difference between the high and low temperatures that day is the gap between the recorded figures on the number line.

The difference can be derived from;

Let the difference be d

d = −3.6∘ - −22.3∘

In algebra, - × -  = +

Therefore,

d = −3.6∘ - −22.3∘ = −3.6∘ + 22.3∘

d = 18.7∘

The difference between the high and low temperatures that day is 18.7∘.
