If u are trying to solve for x is that x=2
Answer:
Step-by-step explanation:
x + 9 = -16
Subtract 9 form both sides
x + 9 - 9 = - 16 - 9
x = -25
Answer:
Step-by-step explanation:
Let us first find the number of possible credit card numbers that can be formed with the numbers 0 - 9.
We want to form a 16 digit number out of 10 digits, so, we have:
There are 
numbers that can be formed.
There are only 100 million valid numbers (
). Let the number of valid numbers be n.
Therefore, the probability of picking a number that is valid is:
P(valid) = n / N
Answer:
No solution
Step-by-step explanation:
This answer has no solution, follow these steps to see how.
First, you add 7 on both sides.
Then you should have 2b > -7 +2b
You see how there is a 2b on both sides? this makes the problem unsolvable.
Say you were to continue though. You would subtract 2b on both sides and end up getting 0 > -7. Therefore there is no solution.
