As given,
Step 1: Pick any three-digit counting number
Lets pick the number 643
Step 2: Reverse the digits of the original number.
So, reverse becomes 346
Now, it says that the difference of these two numbers has a tens digit of 9.
Lets, check:
![643-346=297](https://tex.z-dn.net/?f=643-346%3D297)
So, its true that the difference has a tens digit of 9.
Another example:
Lets take 449
So reverse is = 944
Difference = ![944-449=495](https://tex.z-dn.net/?f=944-449%3D495)
Here also the tens digit is 9.
So, the condition applies to all 3 digit numbers.
Answer:
no there not i´m pretty sure

Answer:
x = 2.5
Step-by-step explanation:
Because the triangles are similar, you can divide the sides and equal the results:
24/6 = 10/x
24•x/6 = 10
24•x = 10•6
24•x = 60
x = 60/24
x = 2.5
