- I’m assuming the expression implies the following:
(1-n)/(n^2 - 1)
The steps goes as follows:
= -(n-1)/(n^2-1) (factored a negative out)
= -(n-1)/[(n+1)(n-1)] (Factored denominator into a difference of squares, but don’t just blindly accept the fact, expand it and you should get the original denominator)
At this point, the (n-1) terms cancel, as you should know: a real number, besides 0, over itself is 1.
= -1/(n+1) , which is the answer
Note: You could also see it as 1/-(n+1) or 1/(-n-1)
It’s going to be A. She was supposed to use distributive property
Monday: 3 1/4 miles
Tuesday: (3 1/4)(2/3) = 2 1/6 miles
Wednesday: (2 1/6)(2) = 4 1/3 miles
Thursday: (4 1/3)(3/4) = 3 1/4 miles
Add them all up: 13 miles
She has not reached her goal, she needs to ride her bike 2 more miles to reach her goal.
Answer:

Step-by-step explanation:
Given
Winning Percentage = 0.444 repeating
Required
Represent as a fraction
Represent the percentage with x

Convert to fraction

Next step, is to convert to fraction repeating
To do this, we simply subtract 1 from the denominator


Simplify to the lowest term: Divide numerator and denominator by 37


Simplify to the lowest term: Divide numerator and denominator by 3


Hence;
There winning fraction is
