X / 9 > 10
- A.
X < 90
- B.
X > 90
- C.
X > 1.11
- D.
X > 10
Correct Answer
B. X > 90Explanation
The correct answer is x > 90 because when dividing x by 9 and comparing it to 10, if the result is greater than 10, then x must be greater than 90.Rate this question:

X / 6 > 7
- A.
X > 42
- B.
X > 7
- C.
X > 1.17
- D.
X < 42
Correct Answer
A. X > 42Explanation
The given inequality states that x divided by 6 is greater than 7. To solve this inequality, we can multiply both sides of the inequality by 6 to isolate x. This gives us x > 42, which means that x is greater than 42. Therefore, the correct answer is x > 42.Rate this question:

X / -9 > 4
- A.
X > -36
- B.
X < 4
- C.
X > -0.44
- D.
X < -36
Correct Answer
D. X < -36Explanation
The correct answer is x < -36. By dividing both sides of the inequality by -9, we can isolate the variable x. When dividing by a negative number, the inequality sign must be flipped. Therefore, x > -36 becomes x < -36.Rate this question:

X / -3 > 2
- A.
X > -6
- B.
X < 2
- C.
X < -6
- D.
X > -0.67
Correct Answer
C. X < -6Explanation
The given inequality states that x divided by -3 is greater than 2. To solve this inequality, we need to multiply both sides by -3 (since we are dividing by a negative number). This reverses the inequality sign. Therefore, we have x < -6, which means that x is less than -6.Rate this question:

X / -3 > -8
- A.
X < -8
- B.
X > 2.67
- C.
X > 24
- D.
X < 24
Correct Answer
D. X < 24Explanation
The given inequality states that x divided by -3 is greater than -8. To solve this inequality, we can multiply both sides by -3, but since we are multiplying by a negative number, the inequality sign will flip. Therefore, we get x < 24 as the correct answer. This means that any value of x that is less than 24 will satisfy the inequality.Rate this question:

X / -5 > -3
- A.
X < 15
- B.
X < 0.60
- C.
X > -3
- D.
X > 15
Correct Answer
A. X < 15Explanation
The given inequality states that x divided by -5 is greater than -3. To solve this inequality, we can multiply both sides by -5, which reverses the inequality sign. This gives us x < 15, meaning that x is less than 15. Therefore, the correct answer is x < 15.Rate this question:

X / 10 > 3
- A.
X > 0.30
- B.
X < 30
- C.
X > 3
- D.
X > 30
Correct Answer
D. X > 30Explanation
The given inequality states that x divided by 10 is greater than 3. To solve this inequality, we can multiply both sides of the inequality by 10 to isolate x. This gives us x is greater than 30. Therefore, the correct answer is x > 30.Rate this question:

X / 9 > 9
- A.
X > 1
- B.
X > 81
- C.
X > 9
- D.
X < 81
Correct Answer
B. X > 81Explanation
The given inequality states that the value of x divided by 9 is greater than 9. To solve this, we can multiply both sides of the inequality by 9, which gives us x > 81. This means that x must be greater than 81 for the inequality to hold true.Rate this question:

When you multiply both sides of any inequality by a negative number, you need to ________ the inequality symbol.
Correct Answer
flipExplanation
When you multiply both sides of any inequality by a negative number, you need to flip the inequality symbol. This is because multiplying both sides by a negative number reverses the direction of the inequality. For example, if the original inequality is "x > 5" and you multiply both sides by -1, you would get "-x < -5". So, flipping the inequality symbol is necessary to maintain the correct relationship between the two sides of the inequality.Rate this question:
