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.

If you use the real Pi , 3.140625 , from a real ratio 201 /64 , you would get 37.6875 inches . All ruler measurements like 1/2 , 1/4, 1/8 ,1/16 … is where the last decimal integer ends in 5 , just like the real Pi . If you use the present day Pi , your decimal integer circumference length keeps getting ever smaller , 10 , 100 , 1000 … in this case you would have a shrinking diameter . You are better off using the real Pi, that i have proven with Quora. Richard Eicholtz

<h3>What is a system of inequalities?</h3>
A system of inequalities is when two or more variables are related, and inequalities are built to find the values of each variable.
In this problem, the variables are given as follows:
- Variable x: number of chocolate chips purchased.
- Variable y: number of pecans sold.
Chocolate chips are $2 per pound and pecans are $5 per pound. She wants to spend at most $25, hence:
