25. ## Algebra

simplify: X - - 2x-5 ___ 4 ______ x-3 x + 2 Sara, use parenthesis, like this: x/(x-5) + (3x+6)/(x+2)

26. ## Algebra

x/(x-3)-4-(2x-5)/(x+2) If the problem is this: x/(x - 3) - 4 - (3x - 5)/(x + 2) ...find a common denominator to start. The common denominator is (x - 3)(x + 2), then convert each term using the common denominator. Here's a start: [x(x + 2)/(x - 3)(x + 2)]

27. ## Algebra

(3x^2+2)/(x^2-4)-(9x-x^2)/(x^2-4) Your problem: (3x^2+2)/(x^2-4)-(9x-x^2)/(x^2-4) Since the denominator is the same, just subtract the numerator: (3x^2 + 2 - 9x + x^2)/(x^2 - 4) -->remember to use the distributive property with the negative over the terms

28. ## Algebra

Solve S=a/(1-r) for r S = a/(1-r) Multiply both sides by 1-r S*(1-r) = [(1-r)*a]/(1-r) Simplify S*(1-r) = a Multiply terms on the left. S - S*r = a Subtract S from both sides. S-S*r - S = a - S Simplify -S*r = a - S Multiply both sides by -1 S*r = -a+S

29. ## algebra

Solve Q=(n-s)/n for n To get you started, multiply both sides by n and go from there. Post your work if you get stuck AND tell us what you don't understand about the next step.
