Answer:
A.10
B.10
C. 10,000
D. 8 hours
Step-by-step explanation:
Firstly, we should know that the numbers are labeled 0-9.
A. 10 digits
B. We already took one digit , but we still have 10 choices left again as numbers can be repeated.
C. For the first number, we have 10C1 choices since we are selecting 1 out of 10 numbers. This is the case for all the 3 renaming numbers. Hence the total number of possible passwords are
(10C1)^4 = 10,000 possible password combinations
D. That is (10,000*3)/60 in minutes = 500 minutes = 500/60 = 8.3333 , approximately 8hrs
Simplifying
7y + -4 = 3y + 6
Reorder the terms:
-4 + 7y = 3y + 6
Reorder the terms:
-4 + 7y = 6 + 3y
Solving
-4 + 7y = 6 + 3y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-3y' to each side of the equation.
-4 + 7y + -3y = 6 + 3y + -3y
Combine like terms: 7y + -3y = 4y
-4 + 4y = 6 + 3y + -3y
Combine like terms: 3y + -3y = 0
-4 + 4y = 6 + 0
-4 + 4y = 6
Add '4' to each side of the equation.
-4 + 4 + 4y = 6 + 4
Combine like terms: -4 + 4 = 0
0 + 4y = 6 + 4
4y = 6 + 4
Combine like terms: 6 + 4 = 10
4y = 10
Divide each side by '4'.
y = 2.5
Simplifying
y = 2.5
Here we need to calculate common denominator so, LCM of 16 & 24
It would be 48
So, final answer is 48
Hope it helped.
