0.888888....
So, Let x = 0.88888....= -----(1)
Now, multiply by 10 on both sides, we get that
Now, Subtracting (1) from (2), we get that
Hence, the decimal 0.88888.... represented by the fraction
Answer:
1 - Option C - 10,000
2 - 3x+5 will be 12 more than 3x-7.

i.e.
Therefore, option C is correct.
2) To find : How much greater is the value of 3x+5 than the value of 3x−7?
Solution ;
Assuming that x is the same value in each equation,
In order to determine the difference between the two values,
We ignore the 3x part as it is the same on both of the equations.
So, from 5 to -7 i.e. 7+5=12.
Therefore, 3x+5 will be 12 more than 3x-7.
