Question

The low temperature in anchorage,alaska,is -15f while the low temperature in lindale,texas,is 32f.write an expression to find the difference between the low temperature in lindane and anchorage

Answer 1

Difference means to subtract, so the difference between the Texas temp and the Alaska temp would be written like this: 32-(-15).  That's a difference of 47 degrees.  If you plotted those points on a number line and counted the units between them, you'd get 47 units.
