Solving Inequalities with Variables on Both Sides

What is the first step in solving the inequality 15B + 6 > 9B - 36?

• Add 9B to both sides

• Subtract 9B from both sides

• Add 6 to both sides

• Subtract 6 from both sides

After moving the variable terms to one side in the inequality 15B + 6 > 9B - 36, what is the resulting inequality?

• 6B + 6 > -36

• 24B + 6 > -36

• 6B - 6 > -36

• 24B - 6 > -36

In the inequality -12K + 28 < 18K + 88, what operation is used to move 18K to the left side?

• Division

• Subtraction

• Addition

• Multiplication

What is the final solution for the inequality -12K + 28 < 18K + 88?

• K > 2

• K < 2

• K > -2

• K < -2

In the inequality 11 + 2C <= 6 - 3C, what is the result after moving 2C to the right side?

• 11 >= 6 + 5C

• 11 >= 6 - 5C

• 11 <= 6 + 5C

• 11 <= 6 - 5C

What is the final solution for the inequality 11 + 2C <= 6 - 3C?

• C <= -1

• C <= 1

• C >= 1

• C >= -1

In the inequality 2(n - 5) >= 30 - 8n, what is the first step?

• Add 8n to both sides

• Subtract 8n from both sides

• Distribute 2 to (n - 5)

• Distribute -8 to (n - 5)

After distributing and simplifying the inequality 2(n - 5) >= 30 - 8n, what is the resulting inequality?

• 2n + 10 <= 30 - 8n

• 2n - 10 <= 30 - 8n

• 2n + 10 >= 30 - 8n

• 2n - 10 >= 30 - 8n

What is the final solution for the inequality 2(n - 5) >= 30 - 8n?

• n >= -4

• n <= -4

• n >= 4

• n <= 4
