Q. w=6+3xy75 w=6+\frac{3 x y}{75} \newlineThe equation gives the quantity w w in terms of the quantities x x and y y . Which of the following equations correctly expresses y y in terms of w w and x x ?\newlineChoose 11 answer:\newline(A) y=25wx6 y=\frac{25 w}{x}-6 \newline(B) y=25w+150x y=\frac{25 w+150}{x} \newline(C) y=25w150x y=\frac{25 w-150}{x} \newline(D) y=25w2x y=\frac{25 w-2}{x}
  1. Given Equation: We start with the given equation:\newlinew=6+3xy75w = 6 + \frac{3xy}{75}\newlineOur goal is to solve for yy in terms of ww and xx.
  2. Isolate Term with y: First, we isolate the term containing yy on one side of the equation by subtracting 66 from both sides:\newlinew6=3xy75w - 6 = \frac{3xy}{75}
  3. Eliminate Denominator: Next, we multiply both sides of the equation by 7575 to eliminate the denominator: 75(w6)=3xy75(w - 6) = 3xy
  4. Solve for y: Now, we divide both sides of the equation by 3x3x to solve for y:\newline75(w6)3x=y\frac{75(w - 6)}{3x} = y
  5. Simplify Equation: We simplify the equation by distributing 7575 and dividing by 3x3x:y=(75w450)(3x)y = \frac{(75w - 450)}{(3x)}
  6. Final Expression: Further simplification gives us:\newliney=25w150xy = \frac{25w - 150}{x}
  7. Compare with Answer Choices: We compare the simplified expression for yy with the answer choices provided:\newline(A) y=25wx6y = \frac{25w}{x} - 6 (Incorrect, as it does not match our expression)\newline(B) y=25w+150xy = \frac{25w + 150}{x} (Incorrect, as it does not match our expression)\newline(C) y=25w150xy = \frac{25w - 150}{x} (Correct, as it matches our expression)\newline(D) y=25w2xy = \frac{25w - 2}{x} (Incorrect, as it does not match our expression)
