1)solve the inequality 3(r11)+15>_9 my answer = r<_13
2)solve the inequality 2<4z+10<_12 my answer = 3<z<_1/2
3)solve the inequality 2x5<_10 or 334x<5 my answer is x<_15/2 or <7
4)solve the inequality 3(absolute bars m4)>6 my answer is m<1 or m>7
5)solve the inequality (absolute bars 3w7)<_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│m4│ > 6
│m4│ > 2
m4 > 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.
