Answer:
You can make 9 three Digit numbers
Step-by-step explanation:
The 9 three digit numbers are:
257
275
752
725
527
572
This can also be easily found out by multiplying the number of digits to the number of digits needed for the number, in this case, there are 3 digits, and the number must have 3 digits in them (without them repeating).
3 digits x 3 needed for the numbers = 9 three digit numbers
When you are multiplying exponents with the same base, you can add the exponents. This is represented as:

In our case we are multiplying exponents with the same base 8 and exponents -7 and 5. The sum of -7 and 5 is -2, so our answer is
.
X=8.33
u have to isolate the x on a side ans the numbers on the other side of the equation
Hi!
What you'll first need to do is subtract 4 from 4 and 13. After doing so, your equation will look like this...
-3x=9
Next, you'll need to divide -3x and 9 by -3. After you've done that, you'll get...
x=-3.
So your answer would be x=-3
I hope this helps!
