what are the sets and subsets of 2/3

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.

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.

describes all the sets and subsets the number 2/3 belongs to and enter the number corresponding to the correct answer as your responce.

enter number 1: rational numbers, integers,whole numbers, natural numbers.
enter number 2: rational numbers, integers, whole numbers.
enter number 3: rational numbers, integers. enter number 4: rational numbers.
enter number 5: irrational numbers.

The correct answer is: 2. Rational numbers, integers, whole numbers.

Abraham needs one-half point to get an a- in math. what rational number can be used to represent the number of points for Abraham to get an a-?(1 point)

The rational number that can be used to represent the number of points for Abraham to get an A- is 1/2.

find the sum of 3/4 and -11/4. reduce your answer to lowest terms.

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.

-12 + -13

-12 + -13 = -25
