-12 is less than 0
The factors of 12 are 1, 2, 3, 4, 6, and 12. None of the factors of 12 are greater than 100.
An inequality requires an inequality sign, usually "less than", "less-than-or-equal", "greater than", or "greater than or equal". Assuming one of these inequality signs is between the "4x" and the "12", for example: 4x < 12, just divide both sides by 4. Just as when you solve equations, the idea is to isolate the variable on one side.
If a plus sign is missing before the 12, any value greater than or equal to 12.If a negative sign is missing before the 12, any value greater than or equal to -12.
X is less than or equal to 4.

The equation 7x-12 is less than 4x plus 36 means just what it says7x - 12 less than 4x + 36To solve this, treat it like ordinary algebra and solve for x, replacing the equals sign with the less than sign. Remember that if you multiply or divide by a negative number, then the less than sign flips over and becomes the greater than sign.7x - 12 less than 4x + 367x less than 4x + 487x - 4x less than 483x less than 48x less than 16
Do you mean 4x^4? not understanding the notation. doctor chuck
It can be Equal or Greater than or less than. 4x4 = 16 4x1 = 4 4x-4 =-16
2(4x + 4) = (4x - 12) 8x + 8 = 4x - 12 8x - 4x + 8 = 4x - 4x - 12 4x + 8 = -12 4x + 8 - 8 = -12 - 8 4x = -20 4x/4 = -20/4 x = -5
No, 4.8 is not greater than 12. Instead, 4.8 is less than 12. The greater between the two can be written as 4.8 < 12
(2x - 4)/(4x + 5) - 12
