True [87]3 years ago
5 0

Answer:

<h2>A. -2y+5x/3x-2y</h2>

Step-by-step explanation:

Given the complex fraction;

-\frac{2}{x} +\frac{5}{y} / \frac{3}{y} - \frac{2}{x} \\

First we will find the LCM of the numerator and the denominator as shown below;

\frac{-2y+5x}{xy} /\frac{3x-2y}{xy}

Then we divide both equation by multiplying the numerator by the reciprocal of the denominator as shown;

= \frac{-2y+5x}{xy} * \frac{xy}{3x-2y}  \\= \frac{-2y+5x}{3x-2y} \\

This gives the required answer

MaRussiya [10]
<h3>Answer:  D) 1/24</h3>

=============================================================

Explanation:

There are 4 digits to pick from and 4 slots to fill, so there are 4! = 4*3*2*1 = 24 different codes possible.

If we want the code to start with 371, then that must mean 5 is the only thing left for that fourth slot. In short, there's only one code that starts with 371 and that code is 3715

We have one code we want (3715) out of 24 total, which is why the answer is 1/24 (choice D)
