### Order the values from least to greatest. 1, |5|, 4, |-8|, -2

• A.

-2, 1, 4, |-8|, 5

• B.

|-8|, -2, 1, 4, |5|

• C.

-2, 1, 4, |5|, |-8|

• D.

1, |5|, 4 |-8|, -2

C. -2, 1, 4, |5|, |-8|
Explanation
The given answer correctly orders the values from least to greatest. The first number is -2, which is the smallest value. Then, the next number is 1, followed by 4. The fourth number is |5|, which is equal to 5, and finally, the largest value is |-8|, which is equal to 8.

### The freezing point is the temperature at which a liquid becomes a solid. The freezing point of butter is 35 degrees and the freezing point of the mercury is -39 degrees.  Which is closer to the freezing point of water at 0 degrees.  (All temperatures are in Centigrade).

• A.

Butter

• B.

Mercury

A. Butter
Explanation
The freezing point of water is 0 degrees Celsius. Since the freezing point of butter is 35 degrees Celsius, it is closer to the freezing point of water compared to mercury, which has a freezing point of -39 degrees Celsius.

### True or False. |-3| < 3

• A.

True

• B.

False

B. False
Explanation
The absolute value of -3 is equal to 3, which is not less than 3. Therefore, the statement |-3| < 3 is false.

Rate this question:

• A.

20 - - 11

• B.

-20 + 11

• C.

11 + 20

• D.

11 - - 20

B. -20 + 11

### Temperatures in the Gobi Desert reach -40 degrees(F) in the winter and 90 degrees (F) in the summer.  Find the range of the temperatures.  In this case,  find the expression that results in correct range value as a positive number.

• A.

-40 - 90

• B.

90 - (-40)

• C.

-40 + 90

• D.

-40 - (-90)

B. 90 - (-40)
Explanation
The correct answer is 90 - (-40). This expression calculates the range of temperatures by subtracting the lowest temperature (-40) from the highest temperature (90), resulting in a positive number.

### Evaluate the expression 4 - a - c  when a = -2 c = 5

• A.

-3

• B.

11

• C.

1

• D.

-1

C. 1
Explanation
The expression 4 - a - c can be simplified by substituting the given values of a and c. So, 4 - (-2) - 5 becomes 4 + 2 - 5 which equals 1. Therefore, the correct answer is 1.

### True / False: Absolute Value is the distance between a number and 0 (zero) on the number line.

• A.

True

• B.

False

A. True
Explanation
The statement is true because the absolute value of a number is the distance between that number and zero on the number line. It is always a positive value, regardless of whether the original number is positive or negative. For example, the absolute value of -5 is 5, as the distance between -5 and 0 is 5 units. Similarly, the absolute value of 5 is also 5, as the distance between 5 and 0 is also 5 units.

Rate this question:

• 8.

### -12 - (-27)  is less than zero.

• A.

True

• B.

False

B. False
Explanation
The expression -12 - (-27) is equivalent to -12 + 27, which equals 15. Since 15 is greater than zero, the statement " -12 - (-27) is less than zero" is false.

Rate this question:

• 9.

### Evaluate the expression (simplify). -6 + (-11) - 2

• A.

19

• B.

3

• C.

7

• D.

-19

D. -19
Explanation
The given expression is -6 + (-11) - 2. To simplify this expression, we can start by adding the two negative numbers -6 and -11, which gives us -17. Then we subtract 2 from -17, resulting in -19. Therefore, the correct answer is -19.

Rate this question:

• 10.

### Evaluate the expression. -5 - (-5)

• A.

0

• B.

-10

• C.

10

• D.

None of the above

A. 0
Explanation
The expression -5 - (-5) can be simplified by applying the rule of subtracting a negative number, which is equivalent to adding the positive number. Therefore, -5 - (-5) becomes -5 + 5, which equals 0.
