Answer:
26*26*26 = 17576 ways to select 3 letters
10*10= 100 ways to select 2 numbers
So then the total number of ways are:
possible ways
Step-by-step explanation:
For this case we assume that we have 26 letters from A to Z and 10 numbers from 0 to 9 .
And we want to calculate the number of possible passwords possible if the password consists of 3 letters followed by 2 digits.
And for this case we can use the multiplication principle of combinatories, since we don't have any restriction about the letters of the numbers we can have repetition of letters or numbers.
For the number of possible letters:
26*26*26 = 17576 ways to select 3 letters
10*10= 100 ways to select 2 numbers
So then the total number of ways are:
possible ways
Answer:
8 Miles
Step-by-step explanation:
Start by creating an equation based off what you know. To start we know it costs $3 just to get a ride + $2 for ever mile we travel (represent this using x)+ the $1 tip we left=$20.
3+2x+1=20
Now you add the like terms together(3+1)
2x+4=20 Subtract the 4 from both sides.
-4 -4
2x=16 Now you just divide each side by 2
_ _
2 2
x=8
Don't forget your label (miles)
Add it tighter and it will make ur number then subtract that
So starting with the question which is
4x-3=2x+13
All you have do is subtract 2x from 4x which is 2x
So now the equation will become
2x-3=13
Minus 3 on both sides So 2x is left over
2x=16
X=8
