Answer:
9x-4 / (x²-4)
Step-by-step explanation:
common denominator is 'x²-4' which is (x-2)(x+2)
the term '7x' already has that denominator but 2/x+2 becomes 2(x-2)/(x²-4)
now you can add 7x to 2(x-2) which is 7x + 2x - 4 or 9x-4 and
your denominator remains as 'x²-4'
Being that their sample size was 10 makes this slightly more straight forward.
first average the overnight percents
(27 + 32 + 34)/3 = 31
so that is the average percent of users that selected overnight.
then apply your average percent to the customer total
.31 * 2755 = 854.05
rounded 854
I think the answer is 4.234.123
4. 180-76=104-36=66
5. 5x + 9x + 26 = 180. 14x + 26 = 180. 14x = 154. x = 11.
6. first answer
7.x=28
