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...
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
Thus the sample solution is not a solution.
A set of three independent equations can be solved for three variables. In this case the...
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...
