Rewrite the expression without parentheses.
12m - (3 + 8m)

The answer would be: (12m - 11m)

Step-by-step explanation: You would just add the numbers in the parenthesis (3+8=11), and there you go, you got the simplified expression 12m- 11m= .

~hope this helped!~

The answer is 1m

Step-by-step explanation:

12 - (3+8m)

(3+8m)=11m

12-11m =1m

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.

im guessing (23,14). hope this : )
