Steven needs to select a 5-digit code to turn off his alarm system. How many different codes can be formed if no digits can be repeated?

Just one

Step-by-step explanation:

if you can’t repeat any digits the first code will go 12345 and just like you run out of digits

100,000

Step-by-step explanation:

There are 5 digits in the number. To form a five digit number , we can have any digit in the 5th place except 0 because 0 will cause the number to be a 4 digit one.

So, the number of ways we can fill the 5th place is 9.

For the 4th place, we can have any digit from 0–9. Same goes for the 3rd, 2nd as well as the One’s place.

Finally we can multiply them and get your answer which is 9*10*10*10*10 which results in 90000.

Unless of course this is an actual code in which the 5th place can be 0. Then that would make the amount 10*10*10*10*10, or 100,000

what are the options? ?

step-by-step explanation:

x= 149. 24+7=31. 180-31=149
