Answer:
9)m≤54
11)x>30
13)y≤40
Step-by-step explanation:
9)m−18≤36
Add 18 to both sides.
m≤36+18
Add 36 and 18 to get 54.
m≤54
11)9x>270
Divide both sides by 9. Since 9 is positive, the inequality direction remains the same.
x=270/9
Divide 270 by 9 to get 30.
x>30
13)y/5≤8
Multiply both sides by 5. Since 5 is positive, the inequality direction remains the same.
y≤8×5
Multiply 8 and 5 to get 40.
y≤40
