(Please Hurry!) Which expression is equivalent to the following complex fraction?

galben [10]

Answer:

The expression equivalent to the given complex fraction is

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

Step-by-step explanation:

An easy way to solve the complex fraction is to solve the numerator and denominator separately.

Numerator:

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

Denominator:

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

Solving the complex fraction:

$[\frac{-2}{x} + \frac{5}{y}] / [\frac{3}{y} + \frac{-2}{x}]\\= [\frac{-2y + 5x}{xy}] / [\frac{3x - 2y}{xy}]$

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

Common terms in the numerator and denominator cancels each other(Cross multiplication) :

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

jalen jogged 10 miles due north, then turned due west and jogged 5 more miles. How msny miles is jalen from his starting point?

Juliette [100K]

Answer:

Jalen is 11.18 miles from his starting point.

Step-by-step explanation:

Given:

Jalen jogged 10 miles due north, then turned due west and jogged 5 more miles.

Now, to find miles Jalen jogged from his starting point.

So, below is the figure attached to describe the scene.

Now, to get the distance of Jalen jogged from his starting point we use pythagoras theorem:

$AB^2+BC^2=AC^2\\\\10^2+5^2=AC^2\\\\100+25=AC^2\\\\125=AC^2$

Using square root on both sides we get:

$11.18=AC\\\\AC=11.18\ miles.$

Therefore, Jalen is 11.18 miles from his starting point.
