Answer:

Well to estimate a decimal the best option would be to round it to.

10 or 11 (For 10.9)

11 (For 11.1)

and since two of them equal 11. 

The estimation would be 11.

I hoped this helped.

Answer:

probably √125

Step-by-step explanation:

so x is between 10.9 and 11.1

What i did was added those to together and then divided them by 2 so that i could find the average between them:

10.9 + 11.1 = 22

22/2=11

so you have 11 as your average.

now what i did was find the value of each answer choice to see which one was closest to 11 and the square root of 125 is just that.
