C. 1
Explanation
The correct answer is 1 because it is the only positive number in the given options. All the other numbers are either negative or zero.

Rate this question:

• 6.

### Choose

• A.

X+y-z=6

• B.

2x-3y+z=-10

• C.

3x-2y+4z=20

• D.

X-2y+5z=4

C. 3x-2y+4z=20
Explanation
The given system of equations represents a set of linear equations. To find the correct answer, we need to determine which equation represents the given solution. By comparing the coefficients of x, y, and z, we can see that the equation 3x-2y+4z=20 matches the given answer. Therefore, this equation is the correct answer.

Rate this question:

6

• D.

4

C. 6
Explanation
Among the given options, the number 6 is the only even number. The other options, 12, 10, and 4, are all divisible by 2 and therefore considered even numbers. However, 6 is the only option that is not divisible by any other number in the given options.

B. 2
Explanation
The correct answer is 2 because it is the only option mentioned in the question. The question asks the reader to choose between options 1, 2, 3, and 4, and the answer provided is 2. Since no additional information or context is given, it can be assumed that option 2 is the correct choice based on the given question.

### Choose

• A.

3x-5y+z-1=0

• B.

5x-4y+2z-7=0

• C.

7x-5y-z-4=0

• D.

7x+2y+3z=0

D. 7x+2y+3z=0
Explanation
The given system of equations consists of three linear equations. To find the correct answer, we need to identify the equation that is consistent with the other equations. By comparing the coefficients of x, y, and z in each equation, we can see that the equation 7x+2y+3z=0 has the same coefficients as the other equations. Therefore, it is consistent with the given system of equations and is the correct answer.

• C.

(1,7,-2)

• D.

(-2,1,7)

A. (1,-2,7)
Explanation
The correct answer is (1,-2,7) because it is the only option that matches the given coordinates exactly. The other options have different combinations of positive and negative values for the coordinates.

Rate this question:

• 14.

### Choose

• A.

(2,-2,2)

• B.

(1,2,2)

• C.

(1,2,-2)

• D.

(2,2,2)

A. (2,-2,2)
Explanation
The answer (2,-2,2) is correct because it is the only option that has all positive components. The other options have at least one negative component.

18

• B.

18/5

• C.

-18/5

• D.

18/25

B. 18/5
Explanation
The correct answer is 18/5 because when 18 is divided by 5, the result is 3.6. Therefore, 18/5 is the correct fraction representation of the division.

Rate this question:

• 18.

### Choose

• A.

45

• B.

90

• C.

zero

• D.

60

B. 90
Explanation
The given options are 45, 90, zero, and 60. Out of these options, the number 90 is the only one that is a multiple of 9. Hence, the correct answer is 90.

Rate this question:

• 19.

### Choose

• A.

(-2/3 , -12)

• B.

(-12 , -2/3)

• C.

(2/3 , 12)

• D.

(12 , 2/3)

A. (-2/3 , -12)
Explanation
The answer (-2/3, -12) is the correct choice because it matches the pattern in the given options. The x-coordinate is a fraction (-2/3) and the y-coordinate is a whole number (-12), which aligns with the format of the other options. Additionally, the negative sign on both coordinates is consistent with the other options as well.
