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.
Answer:
392*pi/3
Step-by-step explanation:
A = r²*angle *pi/ 360 = 14²*240*pi /360 divide by 10 to simplify
196 *24*pi/36 = 196*2*pi/ 3 = 392*pi/3
Answer:
It really depends on what type of equation you are solving.
However, if you're working with an equation that contains variables, it's advised that you should get rid of the variables first before the whole numbers/integers.
