Which of the following expressions are equivalent to (x + y) − z ?

a. z + (x + y)

b. x +(y − z)

c. none of the above

First, let's take a look at the terms in the original expression. Since its just addition and subtraction, we can get rid of the parentheses, leaving behind just .

As long as an answer is made up of a positive , a positive , and a negative , its correct!

Removing the parentheses in choice A leaves us with , which has a positive rather than a negative , so it's incorrect.

Removing the parentheses in choice B on the other hand gives us , which means it's the correct answer! This is a good example of the associative property of addition in action.

the answer is 375 miles

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
