Khan academy has a lot on this sorry I couldn't answer bro
-1/2x < -12
Divide both sides by -1/2
Also because you are dividing by a negative number you need to reverse the inequality sign.
X > 24
This is the simplest way I could explain that complex question.
Answer:
x=±√−9
No real solutions.
Step-by-step explanation:
Step 1: Add 3x^2 to both sides.
27+3x2=−3x2+3x2
3x2+27=0
Step 2: Subtract 27 from both sides.
3x2+27−27=0−27
3x2=−27
Step 3: Divide both sides by 3.
3x2
/3
=
−27
/3
x2=−9
Step 4: Take square root.
x=±√−9
Answer:
and 
Step-by-step explanation:
For this exercise it is important to remember that Whole numbers Set contains the positive numbers and zero with no fractional part and with no decimal part.
Rational numbers are those numbers that can be written as a fraction, in this form:

Where "a" is the numerator and "b" is the denominator. Both are integers.
Then, given the following fraction:

You can express it as a decimal number by dividing the numerator 31 by the denominator 5:

Based on the definition of Whole numbers, you can identify that:

So the given fraction lies between the following Whole numbers:
and
