Answer:

5 is your number

Step-by-step explanation:

Let "a number" = x

2x + 1 = 11

Isolate the x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 1 from both sides

2x + 1 (-1) = 11 (-1)

2x = 11 - 1

2x = 10

Next, divide 2 from both sides

(2x)/2 = (10)/2

x = 10/2

x = 5

5 is your answer

Should the quotient of an integer divided by a nonzero integer always be a rational number? Why or Why not?

lubasha [3.4K]

Yes, it will always be a rational number. I'll expound on this by defining what a rational number is. It is any number that can be expressed as a fraction. Otherwise, it is called an irrational number with a non-terminating decimal expansion. So, although 1/3 has a non-terminating decimal expansion because it is equal to 0.33333333...., it is still a rational number because it can be expressed into a fraction.
