• 1.

### 14= n+12

• A.

2

• B.

4

• C.

12

• D.

14

A. 2
Explanation
The equation 14 = n + 12 implies that n is 2. This can be found by subtracting 12 from both sides of the equation, resulting in n = 2. Therefore, the correct answer is 2.

### 8n=64

• A.

8

• B.

16

• C.

32

• D.

64

A. 8
Explanation
The equation 8n = 64 can be solved by dividing both sides of the equation by 8. This will give us n = 8, which means that when 8 is multiplied by 8, the result is 64. Therefore, the correct answer is 8.

### 10=5r

• A.

2

• B.

3

• C.

4

• D.

5

A. 2
Explanation
The equation 10 = 5r can be solved for r by dividing both sides of the equation by 5. This gives us r = 2, which means that the value of r that satisfies the equation is 2. Therefore, the correct answer is 2.

• 4.

### 15=10-r

• A.

-5

• B.

5

• C.

10

• D.

15

A. -5
Explanation
The given equation is 15=10-r. To solve for r, we need to isolate it on one side of the equation. Subtracting 10 from both sides, we get 5=r. Therefore, the value of r is 5.

Rate this question:

• 5.

### 2x<-30

• A.

X

• B.

X

• C.

X>-15

A. X
Explanation
The given answer, x > -15, is correct because the original inequality states that 2x is less than -30. Dividing both sides of the inequality by 2 gives x < -15. However, since the question asks for the answer in terms of x, we can rewrite the inequality as x > -15. This means that x is any value greater than -15, which satisfies the original inequality.

Rate this question:

• 6.

• A.

X

• B.

X>2

• C.

X

C. X
• 7.

### 6x>-18

• A.

X

• B.

X>-3

• C.

X>3

B. X>-3
Explanation
The correct answer is x>-3 because when we divide both sides of the inequality by 6, the inequality sign remains the same. Therefore, x is greater than -3.

Rate this question:

• 8.

### -7x>-56

• A.

X

• B.

X>7

• C.

X

A. X
