Twice the product of 3and a number exceeds the sum of the number and 80 by 10.what is the number?
Hatshy [7]
First, create an equation with the criteria given.

If we let x be your number,
2(3x) = 80 + x + 10
(2(3x) is twice the product of 3 and x, and if it exceeds x+80 by 10, then we add 10 to x+80 to make the two sides of the equation equal.)

Now, solve for x.

6x=90+x \\ 5x=90 \\ x=18

Each user has a password 6 characters long where each character is an uppercase letter, a lowercase letter, or a digit. Each pas
Lana71 [14]

Answer:

36^{6} -26^6

Step-by-step explanation:

We have 36 characters in total which we can use in order to form a 6 character password.

For each place in this password we have choice of 36 of them, so, the total number of possible passwords of 6 characters is:

36*36*36*36*36*36=36^6

But, we have to exclude all passwords which have no numbers because, by the task, the password must contain at least one digit.

So, now we have choice of 26 characteristic to form password without digits and get 26^6 passwords like that, contained just of letters without digits.

So, the final answer is that we have 36^6-26^6  6-character passwords with at least one digit.
