The current temperature is -8∘F
The current temperature after rising by 12 degrees Fahrenheit from an initial temperature of -20 degrees Fahrenheit can be expressed using an arithmetic expression.
Let T represent the current temperature;
Given that the temperature started at -20 degrees Fahrenheit and then rose by 12 degrees, the expression for the current temperature is:
T = -20 + 12
add the values
T = -8∘F
