Evaluate b - y for b= -13 and y= -50.

Step-by-step explanation:

because you are basically adding -13 to 50 because the minus and the -50 cancel eachother out

linear pair postulates

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
