The height of an airplane as it descends to an airport runway is a quantity which has a unit that is usually rounded to a certain terminating degree of accuracy (i.e. 1, 2, ..., n decimal places)
Thus the set of rational<span> numbers best describes the height of an airplane as it descends to an airport runway.
A rational number is a number which can be represented in the form a/b where a and b are integers. It is usually identified by a terminating or a recurring decimal number.

Answer:
10.4
Step-by-step explanation:
(10x - 4)/5 = 20
(10x - 4) = 20 * 5
10x - 4 = 100
10x = 104
x = 104/10
x = 10.4

Answer:
The answer is that the last marble is red.
Step-by-step explanation:
The answer is that the last marble is red.
We can justify this answer by denial:
For the last marble to be blue, at some stage in the extraction of marbles there must have been n blue marbles and one last red marble.
To remove that red marble, it has to be extracted in one of the following rounds.
If the last red marble is removed, the other marble extracted will be a blue one. Since the marbles extracted are of different color, according to the rules, a red marble must be incorporated into the bag.
So the amount of red marbles in the bag cannot decrease to less than one.
For this reason the last marble is red.

Answer:
x = 11/5
____________________________________________________
Step-by-step explanation:
We are solving for x:
3(4 – 2x) = -x + 1
Distribute the 3 to the 4 and -2x
12 - 6x = -x + 1
Add x to both sides to get the x's together
12 - 5x = 1
Subtract both sides by 12
-5x = -11
Divide by -5. Two negatives turn into a positive.
x = 11/5
