Answer:6
Step-by-step explanation:
using BIDMAS: Brackets,Indices,division,multiplication,addition,subtraction.
1) Firstly you do the problem in the brackets. (-19 - -20) two negatives next to each other make a plus(+) meaning (-19 - -20) = (-19+20) which = 1
2) Next Step is to do the multiplication section. Since we got 1 in place instead of (-19 - -20) we multiply -3 by 1 which = -3.
3) Now the equation we have is 11 + -8 - -3. In BIDMAS both addition and subtraction are equal therefore we can do it in any order. 11 + -8 is the same as 11 - 8 = 3
4) The problem we have now is 3 - -3, like we said before two negatives next to each other make an addition sign(+) so 3 - -3 = 3+3 = 6, therefore getting the answer 6.

Answer:
The solution set to the absolute value is:
or 
Negative real numbers are not included in the solution set, as for 
, 
.
Step-by-step explanation:
From Mathematics, we know that absolute values are defined by the following characteristics:
1) For 
, 
2) For ,
Then, if , then the solution set to the absolute value is:
or
Negative real numbers are not included in the solution set, as for , .
5,000 × 3.8%= 19,000×18= 342,000 × 40 = 13,680,000
Square 12.1, and subtract 121 from both sides.
Complete the subtraction on the right side.
This is the solution.
