Answer: B) 6</h3>
===============================================
Explanation:
Add the equations by adding the terms straight down.
The x terms add to x+x = 2x.
The y terms add to y+(-y) = y-y = 0y = 0, so the y terms go away
The constants add to 5+7 = 12
The z terms add to -z+z = 0z = 0 and those go away as well
After all that adding, we have 2x = 12 which solves to x = 6 after dividing both sides by 2.
1) 11 1/8
2) 5/7
3)it would be 233/3 but since that isn't your option try going with 23/3
4) 10 / 16
5) 9/3 = 3 (aka 3/1 ) then 3/9 = 0.3.
Answer for number 5 ⬇
Therefore 9/3 would be your greatest
~the fractions doesn't equal each other~{meaning that the equal sign wouldn't be your answer} ~
~3/9 Would be lesser than 9/3~
~just make the fraction into division .it might help ~
~~~~~~~~~~~~~`~~~~~~~~~~~~~~~~~~~~~~~~~~~
For improper fraction just multiply and add
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Looking for the equivalent of the fractions... try dividing as well
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Example of a improper fraction
Problem : 12 3/5
Work: 12(5) = 60
60 +( 3 )= 63
Answer : 63/ 5
(note: don't worry about the example .... its not apart of the questions you asked.. but you can if you want to ... don't get me wrong.. if it was helpful you can use it )

99 10,581/250,000 No time explain, there's a little time to explain but not a lot of time to explain but hope this helps without explanation! Btw this is the simplified answer
D. (9x-4)^2
You can find this by taking the square roots of the outside numbers and multiplying them by each other and 2 to see if they equal the middle number.
