Step-by-step explanation:
it is calculated by chain rule,...
I’m pretty sure it’s A.) Updating directions to your office..
5x + 3 = 3x + 11
• first put all the x-values on one side and the rest on the other
Remember: when the number moves to the other side of the equal sign the sign (+ OR - switches. For ex: the 3 on the left becomes negative when moved to the right side of the equal sign)
5x - 3x = 11 - 3
• subtract left and right sides separately
2x = 8
• divide both sides by 2 to solve for x
2x/2 = 8/2
x = 4 (final answer)
An irrational number.
Example: Pi. Pi doesn’t have an ending as far as we know, so it cannot be written as a fraction.
