me! : )

C. Rational

Step-by-step explanation:

While this number technically has no end, it repeats. This puts it in a special case.

First, lets look at the decimal portion and ignore the integer with it.

When looking at ..., we can convert this into the fraction

Now, we can multiply -12 by the denominator and add them together to get

As this number can be written as a fraction, it is a rational number.

C

Step-by-step explanation:

A: a whole number is a positive number (not including 0) that does not have anything after the decimal.

B: an integer is 0, all the + and all the minus numbers that have nothing after the decimal.

D: an irrational number has an unending decimal like pi.

C: has a terminating decimal and is minus. It is C, rational.

1. First step: To get a term of x by itself, add 5 to both sides

Second step: This will become 3x<24

Third step: To separate 3x, divide everything by 3: 3x÷3 < 24÷3

Step four: x < 8

2. First subtract both sides by 12: - 2x + 12 - 12 < - 4 - 12

Second: This becomes - 2x < -16

Third: Divide by -2 to get x by itself - 2x ÷ - 2 > -16 ÷ - 2 Note: If you divide by a negative number, the inequality sign switches. This is a really important step that most students forget.

Fourth: x>8

Note: Try plugging in values when you are done if you are uncertain you have the right answer.
