Math Problem Statement
Solution
I can see the inequalities from the image you uploaded. Let me go through each one and solve them step-by-step:
Problem 11:
-
Distribute the :
-
Subtract 6 from both sides:
-
Divide by 10:
or
Problem 12:
-
Distribute the :
-
Combine like terms:
-
Add 30 to both sides:
-
Divide by (reverse the inequality):
Problem 13:
-
Distribute the :
-
Combine like terms:
-
Subtract 14 from both sides:
-
Divide by (reverse the inequality):
Problem 14:
-
Distribute the on both terms:
-
Combine like terms:
-
Subtract 14 from both sides:
-
Divide by 8:
Would you like a more detailed breakdown or explanation for any of these? Here are 5 related questions to deepen understanding:
- How do we reverse inequality signs when dividing by a negative number?
- What is the difference between solving an equation and an inequality?
- How can we represent these solutions on a number line?
- What would happen if we change the inequality symbols in these problems?
- Can inequalities have multiple solutions, and how are they represented?
Tip: Always remember to reverse the inequality sign when you multiply or divide both sides by a negative number.
