Answer:

$y = \frac{x}{2}+15$ will be the equation that can be used to predict the number of minutes after 4:00 pm she will arrive at her destination.

Step-by-step explanation:

Let x represent the time, in minutes, of her original flight plan.

Let y represents the time, in minutes, of her new flight plan.

The time of Original flight schedule = 4:00 pm

The number of minutes delayed by Original flight = 15 minutes

As the new flight plan is two times faster than original flight plan.

So, the equation of new flight plan will be:

$y = \frac{1}{2}x$

$y = \frac{x}{2}$

But, the original flight plan was delayed by 15 minutes. Hence, the equation to predict the number of minutes after 4:00 pm she will arrive at her destination will become:

$y = \frac{x}{2}+15$

So, $y = \frac{x}{2}+15$ will be the equation that can be used to predict the number of minutes after 4:00 pm she will arrive at her destination.

Answer:

$x = - \frac{25}{3}$

Step-by-step explanation:

$\frac{10}{3} = \frac{x}{( - \frac{5}{2}) }$

<h3>i) simplify the complex fraction</h3>

$\frac{10}{3} = - \frac{2x}{5}$

<h3>ii) simplify the equation using cross multiplication</h3>

$5(10) = - 2x(3)$

$50 = - 6x$

<h3>iii) swap the sides of the equation</h3>

$- 6x = 50$

<h3>iv) divide both sides of the equation by -6</h3>

$\frac{ - 6x}{ - 6} = \frac{50}{ - 6}$

$x = - \frac{50}{6}$

<h3>v) simplify the fraction</h3>

$x = - \frac{25}{3}$
