Answer:

$n = -8$

Step-by-step explanation:

Solve for $n$ :

$20 = 4 + 4n - 6n$

-Combine like terms:

$20 = 4 + 4n - 6n$

$20 = 4 - 2n$

-Switch sides so that variables can be on the left side of the equation:

$20 = 4 - 2n$

$4 - 2n = 20$

-Subtract both sides by $4$ :

$4 - 4 - 2n = 20 - 4$

$-2n = 16$

-Take $-2n$ and divide them on both sides of the equation:

$\frac{-2n}{-2} = \frac{16}{-2}$

$n = -8$

So, the value of $n$ is $-8$ .

The positive integers $1,$ $2,$ $3,$ $\dots$ are listed in order. What is the $1000^{\rm th}$ positive integer with an odd numbe

Ghella [55]

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 $9\times10^{n-1}$ integers with $n$ 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.
