Answer: The number is 12.
Step-by-step explanation:
Since we have given that
Sum of two digits = 12
Let the one's digit be 'x'
Let the ten's digit be '12-x'
So, Original number would be
![x+10(12-x)\\\\=x+120-10x\\\\=-9x+120](https://tex.z-dn.net/?f=x%2B10%2812-x%29%5C%5C%5C%5C%3Dx%2B120-10x%5C%5C%5C%5C%3D-9x%2B120)
If 16 is added to the number, then one of the digit is four times the value of the other.
According to question, we get that
![-9x+120+16\\\\=-9x+136](https://tex.z-dn.net/?f=-9x%2B120%2B16%5C%5C%5C%5C%3D-9x%2B136)
so, the one's digit be 'x'.
Let the ten's digit be '4x'.
so, New number would be
![10x+4x=14x](https://tex.z-dn.net/?f=10x%2B4x%3D14x)
According to question, it becomes,
![14x=-9x+136\\\\14x+9x=136\\\\23x=136\\\\x=\dfrac{136}{23}=12](https://tex.z-dn.net/?f=14x%3D-9x%2B136%5C%5C%5C%5C14x%2B9x%3D136%5C%5C%5C%5C23x%3D136%5C%5C%5C%5Cx%3D%5Cdfrac%7B136%7D%7B23%7D%3D12)
So, the number would be
![-9x+120=-9\times 12+120=-108+120=12](https://tex.z-dn.net/?f=-9x%2B120%3D-9%5Ctimes%2012%2B120%3D-108%2B120%3D12)
Hence, the number is 12.
If you throw a die, this is what you could get:
1, 2, 3, 4, 5 or 6.
--------------
Odd Numbers: 1, 3, 5
Numbers less than Three: 1, 2
---------------
Possibility of getting 1, 2, 3 or 5:
4/6 which translates into 2/3.

Answer:
2/3
Comment if you want me to give you the step by step thank you
We are given the following conversion factor:
![10\text{ miles=}16\text{ km}](https://tex.z-dn.net/?f=10%5Ctext%7B%20miles%3D%7D16%5Ctext%7B%20km%7D)
We are asked to determine how many miles are 140 km. To do that we use the quotient of the conversion factor where the unit we want to convert to is in the numerator and the given unit in the denominator. Since we want to find miles we use the following quotient:
![\frac{10\text{ miles}}{16\text{ km}}\times140\operatorname{km}](https://tex.z-dn.net/?f=%5Cfrac%7B10%5Ctext%7B%20miles%7D%7D%7B16%5Ctext%7B%20km%7D%7D%5Ctimes140%5Coperatorname%7Bkm%7D)
Solving the operations we get:
6xy^2 - xy + 8 + 12y is a polynomial of degree 3
