11. D because when you multiply or divide you switch the sign
12. B because she its less than or equal to the 20 dollars
13. 4 (x-4) < 12 4x-4 <12 +4 to each side 4x < 12 divide 4 from each side and get x=3
14. 8-a > -3 (2 -6) 8-a > -6-18 8-a > 12 -8 on each side -a> 4 then take the negative sign off the a and move it to 4 making the answer a< -4 because when you take the negative off of the a its like dividing it so then you flip the sign
hope this helps! :)
