To get the value of n in the problem above, divide the sum by the number of n's added together. From the given, n + n = 24, there are only two n's added together. Hence, divided 24 by 2. The answer to this item is 12.
When 2 digits are next to each other, the place value relationships of both numbers are 10 times greater. Why because in a place value of ones, tens, hundreds, thousands, hundred thousands, etc. The value of ones multiplied by 10 is equals to tens. The value of tens multiply by 10 is equals to hundreds. The value of hundreds multiply by 10 is equals to thousands and the value of thousands multiply by 10 is equals to hundred thousand.

The simplest ratio is 1/3. Equivalent ratios would be 3/9 and 5/15.
50 = x^2 - 9x + 14
x^2 - 9x + 14 - 50 = 0
x^2 - 9x - 36 = 0
(x - 12)(x + 3) = 0
x - 12 = 0
x = 12 <==
x + 3 = 0
x = -3......not this one
Out of all the numbers from 1 to 80, there are (80-20)/(80) = 60/80 = 0.75
of them that are greater than 20 .
So every time you pick one at random, there a 75% chance that it will be
greater than 20.
If everything works out according to pefectly random probabilities, then
in 180 selections, 75% of them = (0.75 x 180) = <em>135 of the selections</em>
would be numbers greater than 20 .
