Simplify the expression, show your work
Mila [183]

Answer:

\dfrac{-y(2x^2 + y)}{x(6x - 5y^2)}

Step-by-step explanation:

\dfrac{\frac{1}{x^2}+\frac{2}{y}}{\frac{5}{x}-\frac{6}{y^2}} =

To eliminate the denominators of the main numerator and denominator, we multiply the numerator and denominator of the main fraction by the LCD of all small denominators.

The LCD of x^2, y, x, and y^2 is x^2y^2.

= \dfrac{x^2y^2 \times (\frac{1}{x^2}+\frac{2}{y})}{x^2y^2 \times (\frac{5}{x}-\frac{6}{y^2})}

= \dfrac{y^2 + 2x^2y}{5xy^2 - 6x^2}

= \dfrac{y(y + 2x^2)}{x(5y^2 - 6x)}

= \dfrac{-y(2x^2 + y)}{x(6x - 5y^2)}

Martha works in a toy shop and earns $44 per day. She earns an extra $2 for each toy she sells. If Martha wants to earn at least
pantera1 [17]
Martha's total earnings is the sum of her fixed pay pay day and the extra she gains based on the number of toys she sold. Her total earnings may be expressed as,
 
                                        44 + 2n 

Since she desires to earn $80 or more, the inequality is expressed as
 
                                         44 + 2n ≥ 80

Solving for n from the inequality,
 
                                                    n ≥18

Thus, the answer is the first choice.
