There are 9 positive integers with 1 digit (1 - 9).
There are 90 integers with 2 digits (10 - 99).
There are 900 integers with 3 digits (100 - 999).
There are 9000 integers with 4 digits (1000 - 9999).
And so on. It stands to reason that there are
integers with
digits.
Now,
1000 = 9 + 900 + 91
so the 1000th positive integer with an odd number of digits is the 91th number with 3 digits, which is 190.

I put the letters here in order, a clockwise order starting at Q.
If you look at our diagram you will see that RT and QS are actually the diagonals of this rectangle.
The diagonals of a rectangle are congruent.
We have the measurement of RT = the measurement of QS.
That is we have this equation: 4x-16=x+5.
4x-16=x+5
Subtract x on both sides:
3x-16= 5
Add 16 on both sides.
3x = 21
Divide both sides by 3.
x = 7
