This is a conversion from one American standard unit to another, NOT from American standard to metric. "Multiply to change larger units to small units." is a valid rule only if you use specific conversion factors. The best way to change units is to use Dimensional Analysis...

14x-2>2(6x-8)   14x-2>12x-16   2x>-14   x>-7

No.  We have the Constitution, laws passed by Congress and Regulations written by a myriad of Executive organizations such as the FCC, ICC, FDA and many others.  There are bound to be conflicts within such a huge body of laws.  Then there is a similar set of State groups that create...

the sample solution is not a solution.   x+2y-z=3  using the sample solution   2+6-0=?3   8≠3 Thus the sample solution is not a solution. A set of three independent equations can be solved for three variables.   In this case the...

OC=5X=5(0.5)=2.5

3.1 x 10^11 (answer)

This is scientific notation:  A number multiplied by ten to a power.  Moreover, It is Standard Scientific Notation: the number in front is > or = to 1 and <10

Don't get confused by the fact that a is negative and c=0.  This is standard factoring. ax^2+bx+c = (ax+b)(x)     Remember: c=0

If someone tells you that the answer is x=5/2 then they should be able to show you how to get that answer.  My answer is different. (x-2)/3 + (x-2)/4 = 7/24  I approach this by expressing everything as 24ths.  Thus I must multiply the first term by 8/8 and the second term...
