5/1? Im not sure if i am right
Answer:
First do the case in which none of the digits is 0.
There are 9 ways to choose the digit that repeats 3 times and 8 ways to pick the other, after this there are 4 ways to order the digits. So 9×8×4.
Now we look at the cases in which the digit 0 repeats 3 times. Clearly the 9 numbers are 1000,2000,3000,…,9000.
Lastly we look at the cases in which 0 appears once. There are 9 ways to pick the other digit and 3 ways to order.
So the final answer is 9×8×4+9+9×3.
Answer:
x=4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
Step 2: Add 25x to both sides.
Step 3: Subtract 16 from both sides.
Step 4: Divide both sides by 9.
Rounded to the nearest thousandth
3n = 3 (0.333) = 0.999 = 1
-n/3 = -0.333/ 3 = -0.111
2n = 2(0.333) = 0.666 = 0.667
