The answer for this problem would be 213
Suppose the one's digit is x, the ten's digit is y. the original number is 10y+x, the reversed number is 10x+y
x+y=13
(10x+y)=(10y+x)-9 =>9y-9x=9 =>y-x=1
Add the two equation to solve: 2y=14 =>y=7
x=13-7=6
the original number is 76.
I dont really know... I will figure it out.
Answer:
1 
Step-by-step explanation:
There are a total of 2 friends, if they have 3 cereal bars and want to split it equally then we simply need to divide the number of cereal bars by the number of friends which would give us the number of cereal bars that each individual will get, which will be represented by x
x = 3 / 2
x = 1 
Finally, we can see that each friend will get a total of 1 and a half of a cereal bar.
Answer:
x = 54
Step-by-step explanation:
According to Vertical Angle Theorem,
(3x-52)* = (2x+2)*
x = 54*
