Find the sum of 12a + 7b, −6a − 9, and 14a − 12b.
Ivan
The answer is:  [A]:  " 20a − 5b − 9 " .
______________________________________
Explanation:
_______________________________________________
  (12a <span>+ 7b) + (−6a − 9) + (14a − 12b) =
 
   12a </span><span>+ 7b  +  1(−6a − 9) + 1(14a − 12b) =
</span>    
   12a + 7b + (1*-6a) + (1*-9) + (1*14a) + (1* -12b) =
      
    12a + 7b − 6a − 9 + 14a − 12b =  ?

Combine the "like terms:

12a − 6a  + 14a = 20a ; 

7b − 12b =  - 5b ;

and then we have "-9" ;
_____________________________________________________
So, write as:   " 20a − 5b − 9 " ;  which is:  Answer choice:  [A].

A total of 24 out of 40 sixth graders buy hot lunch each day. What percent of these students do not buy hot lunch each day?
Goshia [24]
60% of student don't buy a hot lunch. 
The simple way of doing it is by taking both numbers and dividing them.  24 divided by 40= 0.6  Since percents are part of a whole, we need to multiply by 100  0.6 times 100 equals 60.
Easy and accurate.
