Answer:
D. m+n=n+m
Step-by-step explanation:
Communitive property of addition just changes the order of the addend and the sum stays the same.
4.99 /2 = 2.495
9.85/6 =1.641666666
The 6 oz is a better deal
Answer:
<u>answer is C ( </u>
<u> )</u>
Step-by-step explanation:
so here is how you do it.
first you need to find out what 
is
which is the same as 3 X 3 X 3 X 3 X 3 X 3 X 3 X 3
the answer to that is 6,561
then you have to square root that
which looks like this
which is 81
which means that you have to find the same expression that equals to 81
I then did (C) to see if the answer will be 81 and it is. so your answer is C
It is 2. (4x - 1) which is false!
First put a bubble around 5x-7. Now you plug that into the problem. -3x-2
(5x-7)=12. now times the -2 by 5x which is -10x. and then times the -2 by -7 which is 14. so now you have -3x-10x+14=-12. add the -3x and -10x. -13x. Add the 14 over. -13x=2. Now dived by -13, which gives us x=-0.15
Now you take that a plug it into the -3x-2y=-12. So that it looks like this -3(-0.15)-2y=-12
Now times the -3 by -0.15 to give us 20 -2y=-12. Now 'kill' the 20, so that it looks like this -2y=-32. Now you divide by -2 and get y=16.
Now your ordered pair is (-0.15,16)
