Good morning, have some question...

Good morning, have some question that I need to see if you will do for me:

1) x/3 = 4/x+1

2) -3/x = x/ -3

reduce to lowest term-assume variable represent only number for which the denominators are nonzero:

3) a^2 -b^2 / a-b

4) -2x -8 /x^2 + 2x -8

5)3/a^2 +a * 2a + 2/6

6) w^2 -1/(w-1)^2 * w-1/w^2 +2w +1

7) -7yt/2at = ---/ 2ayz

8)find LCD for rational expression, convert rationa expression into equivalent reational expression with LCD as denominator 4/a-6 , 5/6-a

9)lowest terms

a+7/a-4 +9-5a/a

10)2/x-3 + 3/3-x

Simplify and reduce to lowest terms

11)1/9 + 1/3x/ x/9 - 1/x

12. ab + b^2/4ab^5

________________

a+b/6a^2 b^4

need these word out step by step:

Use a proportion to sove each problem:

13) Fast Food: If four out of five doctors perfer fast food, then at a convention of 445 doctors, how many prefer fast food?

14) The anciet Greeks thought that the most pleasing shape for a retangle was one for which the ratio of the length was approximately 8 to 5, the golden ratio. If the length of a rectangular painting is 2 foot longer than it width, then for what dimensions would the length and width have the golden ration?

15) To estimate the size of the bear population in the Keweenaw Peninsula, conservationists captured, tagged, and released 50 bears. One year later, a random sample of 100 bears included only 2 tagged bears. What is the convervationists estimate of the size of the bear poplulation?

Would like to have these by Wednesday if possible.

Need anyting else just let me know.

Thanks
