1. he correct statement is:

   “The temperature started at 78 degrees and decreased by 6 degrees, then decreased by 5 degrees.”

   Which statement best describes this expression?

   Here we have the expression:

   78+(-6)-5

   So we start at 78, then we subtract 6, and then we subtract 5.

   This means that the initial temperature is 78, then it decreases by 6 degrees, and then it decreases again by 5 degrees.

   Then the correct statement is:

   “The temperature started at 78 degrees and decreased by 6 degrees, then decreased by 5 degrees.”

   Which is the third statement counting from the top.
