Help Please

Abigail reads the temperature of a mixture in an experiment. The temperature of the mixture is 5.7ºF. After 4 hours, she reads the temperature of the solution again. The temperature of the mixture is now −1.4°F.

Abigail plots the points on a number line to determine the temperature change between these two readings.

How much did the temperature decrease?

Respuesta :

7.1 degrees.
5.7-(-1.4)
5.7+1.4= 7.1

Hope I helped!
