The set, denoted as A, with the single element of 2/3 is {2/3}.

Any subset of A can be an empty set, {2/3}, or both combined.

To find the sum of 3/4 and -11/4, we add the numerators while keeping the denominator the same:

(3/4) + (-11/4) = (3 - 11)/4 = -8/4

The answer, -8/4, can be simplified to its lowest terms by dividing both the numerator and denominator by their greatest common divisor, which is 4:

(-8/4) ÷ 4/4 = -2/1 = -2

Therefore, the sum of 3/4 and -11/4, reduced to lowest terms, is -2.

To find the temperature now, we need to subtract the change in temperature from the initial temperature.

13 degrees Celsius - 18.6 degrees Celsius = -5.6 degrees Celsius

Therefore, the temperature now is -5.6 degrees Celsius.

To find the expression -492.89 - (-871.78), we can use the additive inverse property, which states that subtracting a number is the same as adding its opposite.

So, we can rewrite the expression as follows:

-492.89 + 871.78

= 378.89

Therefore, the result is 378.89.

To determine the distance between -18.26 and -2.45 on a number line, we subtract the smaller value from the larger value:

|-18.26 - (-2.45)| = |-18.26 + 2.45|

= |-15.81|

= 15.81

Therefore, the distance between -18.26 and -2.45 on a number line is 15.81.

To subtract -15 from 24, we can use the additive inverse property and rewrite the expression:

24 - (-15) = 24 + 15

= 39

Therefore, the result is 39.

To simplify the expression 17 4/9 + 5/9 - 8 - 10, we first convert the mixed number (17 4/9) into an improper fraction.

17 4/9 = (17 * 9 + 4)/9 = 157/9

Now we can rewrite the expression as follows:

157/9 + 5/9 - 8 - 10

Combining like terms, we get:

(157 + 5)/9 - 18

= 162/9 - 18

To subtract fractions, we need a common denominator, which in this case is 9. So we rewrite 18 as 162/9:

162/9 - 162/9

Now, we can subtract the numerators:

(162 - 162)/9

= 0/9

Finally, we simplify the fraction:

0/9 = 0

Therefore, the result is 0.

To find the change in temperature during the three hours between 9 a.m. and noon, we need to subtract the initial temperature from the final temperature.

Final temperature - Initial temperature = Change in temperature

-1.6 degrees Celsius - (-5.8 degrees Celsius) = Change in temperature

To simplify the calculation, we can rewrite the subtraction as addition by taking the additive inverse of -5.8 degrees Celsius:

-1.6 degrees Celsius + 5.8 degrees Celsius = Change in temperature

= 4.2 degrees Celsius

Therefore, the change in temperature during the three hours is 4.2 degrees Celsius.

This means that the temperature increased by 4.2 degrees Celsius from -5.8 degrees Celsius at 9 a.m. to -1.6 degrees Celsius at noon.
