First you would find a common denominator, in this case it is 60. So you would multiply 11 and 12 by 5 and 7 and 20 by 3, getting this equation.


55/50 - 21/60


From this equation you would subtract 21 by 55. Getting this fraction as a final answer. 

31/60.

Also if you want a decimal it would be 31 divided by 60. Then you would get your decimal answer being:

0.516666666666666666666666666666666666666666....

The common denominator of both fractions is 60.. You can convert 11/12 into 55/60 by multiplying both the numerator and denominator by 5, and you can also convert 7/20 into 21/60 by multiplying both the numerator and denominator by 3.  55/60-21/60= 34/60, simplified to 17/30.

Hope it helped!

Will the sum of two linear expressions each with an x-term , always,sometimes,or never have an x-term ? Explain your reasoning
Licemer1 [7]

Sometimes it will, and sometimes it won't.

I reason as follows:

(21 + x)  +  (30 + 2x)  =  51 + 3x      has an 'x' term

(42 + x)  +  (30 - x)  =  72                  has no 'x' term.
