2)solve the inequality -2<4z+10<_12 my answer = -3<z<_1/2

3)solve the inequality 2x-5<_10 or 33-4x<5 my answer is x<_15/2 or <7

4)solve the inequality 3(absolute bars m-4)>6 my answer is m<1 or m>7

5)solve the inequality (absolute bars 3w-7)<_2 my answer = w<_3

in #1 your second last line would be

-3x ≤ -39 so

x ≥ 13 , remember that you have to reverse the inequality sign when multiplying or dividing by a negative.

#2 is good

#3 same error as in #1, you forgot to change the inequality sign

answer should be x≤15/2 or x>7

#4:

3│m-4│ > 6

│m-4│ > 2

m-4 > 2 OR -m+4 > 2

m > 6 OR -m > -2

m > 6 OR m < 2

for #5 I got

w ≤ 3 AND x ≥ 5/3 , see if you can obtain that same result.
