M=−(4+m)+2 solve for m.

m=-1

Step-by-step explanation:

M=-(4+m)+2

M=-4-m+2

m+m=-4+2

2m=-2

m=-1

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
