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 we divide x by 9 and the result is greater than 10, it means that x must be greater than 90. If x were less than 90, the result of the division would be less than 10.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 / -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 can multiply both sides by -3, but since we are multiplying by a negative number, the inequality sign will flip. This gives us x < -6, which means that x is less than -6. Therefore, the correct answer is x < -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, which reverses the inequality sign. Therefore, we get x is less than 24. 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 to get x by itself. When we multiply both sides by -5, we need to reverse the inequality sign. So, x is less than 15, which means 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 correct answer is x > 30 because if we divide both sides of the inequality x / 10 > 3 by 10, we get x > 30. This means that x must be greater than 30 in order for the inequality to be true.Rate this question:

- A.
X > 1
- B.
X > 81
- C.
X > 9
- D.
X < 81
Correct Answer
B. X > 81Explanation
The given inequality states that x divided by 9 is greater than 9. To solve this inequality, we can multiply both sides of the inequality by 9, which gives us x is greater than 81. Therefore, the correct answer is x > 81.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 by a negative number reverses the order of the numbers. For example, if we have the inequality 3 > 2 and we multiply both sides by -1, we get -3 < -2. So, in order to maintain the correct order of the numbers, we need to flip the inequality symbol.Rate this question:

Solve: y - 16 < 12
- A.
Y < -28
- B.
Y > 28
- C.
Y < 28
Correct Answer
C. Y < 28Explanation
The given inequality is y - 16 < 12. To solve this inequality, we can add 16 to both sides to isolate the variable y. This gives us y < 28, which means that y is less than 28. Therefore, the correct answer is y < 28.Rate this question:

Write an inequality for "a number minus 14 is more than 35."
- A.
14 - n ≥ 35
- B.
N - 14 ≥ 35
- C.
N - 14 < 35
- D.
N - 14 > 35
Correct Answer
D. N - 14 > 35Explanation
The correct answer is n - 14 > 35. This inequality represents the statement "a number minus 14 is more than 35." By subtracting 14 from a number (n) and setting it greater than 35, we are expressing that the result of the subtraction is greater than 35.Rate this question:

Write an inequality for "six times a number is at most 91."
- A.
6k ≤ 91
- B.
6k ≥ 91
- C.
6k < 91
- D.
6k > 91
Correct Answer
A. 6k ≤ 91Explanation
The inequality 6k ≤ 91 represents the statement "six times a number is at most 91." This means that when the number is multiplied by 6, the result is less than or equal to 91.Rate this question:

Solve. x - (-4) < 12
- A.
X < 8
- B.
X < 16
- C.
X > 8
- D.
X > 16
Correct Answer
A. X < 8Explanation
The given inequality is x - (-4) < 12. Simplifying this, we get x + 4 < 12. Subtracting 4 from both sides, we have x < 8. Therefore, the correct answer is x < 8.Rate this question:

- A.
Y < -13
- B.
Y < -19
- C.
Y > -19
- D.
Y > -13
Correct Answer
C. Y > -19Explanation
The given inequality is y - (-3) > -16. Simplifying this, we get y + 3 > -16. Subtracting 3 from both sides, we have y > -19. Therefore, the correct answer is y > -19.Rate this question:

- A.
Z ≥ 6
- B.
Z ≥ 16
- C.
Z ≤ 16
- D.
Z ≥ -6
Correct Answer
B. Z ≥ 16Explanation
The inequality z - 5 ≥ 11 can be solved by adding 5 to both sides of the inequality, resulting in z ≥ 16. This means that any value of z that is greater than or equal to 16 satisfies the inequality.Rate this question:

- B.
X > -6
- C.
X > 2
- D.
X > 18
Correct Answer
C. X > 2Explanation
The given inequality is 6x > 12. To solve for x, we divide both sides of the inequality by 6, resulting in x > 2. This means that any value of x that is greater than 2 will satisfy the inequality.Rate this question:

- B.
B < -9
- C.
B > 9
- D.
B < 9
Correct Answer
A. B > -9Explanation
The given inequality is 4b > -36. To solve this inequality, we divide both sides by 4 (since it is a positive number), giving us b > -9. This means that b is greater than -9.Rate this question:

- A.
K ≤ -4
- B.
K ≥ 4
- C.
K ≤ 4
- D.
K ≥ -4
Correct Answer
D. K ≥ -4Explanation
The given inequality states that -5k is less than or equal to 20. To solve for k, we need to isolate it on one side of the inequality. By dividing both sides of the inequality by -5, we get k greater than or equal to -4. Therefore, the correct answer is k ≥ -4.Rate this question:
