6-x•11 is the answer u r looking for
x=2 is only solution while x=1 is extraneous solution
Option C is correct.
Step-by-step explanation:
We need to solve the equation and find values of x.
Solving:
Find the LCM of denominators x-1,x and x-1. The LCM is x(x-1)
Multiply the entire equation with x(x-1)
Now, factoring the term:
The values of x are x=1 and x=2
Checking for extraneous roots:
Extraneous roots: The root that is the solution of the equation but when we put it in the equation the answer turns out not to be right.
If we put x=1 in the equation, the denominator becomes zero i.e
which is not correct as in fraction anything divided by zero is undefined. So, x=1 is an extraneous solution.
If we put x=2 in the equation,
So, x=2 is only solution while x=1 is extraneous solution
Option C is correct.

Answer:
54 mph
Step-by-step explanation:
Let s represent the slower speed. The product of speed and time is distance, which did not change between the two trips. So, we have ...
1.8(s +6) = 2(s)
10.8 = 0.2s . . . . eliminate parentheses, subtract 1.8s
54 = s . . . . . . . . divide by 0.2
