Paul and Dana both want to find the change from the 6 AM temperature to the new 12 PM temperature . Paul says that you can use a number line and add the distances from to the 6 AM temperature and from to the new 12 PM temperatureDana says that you can subtract - 1.4 from the new 12 PM temperature . Is either Paul or Dana correct? Explain your reasoning and find the change in temperature

Both, Diana and Paul are correct. The change in the temputare is 3.9 f. The new 12pm temperature is 3(-0.5) = 2.5 F. which is on the opposite side of  OAS the GAM temputare -1.4.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
