Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels 18 miles per hou

11111nata11111 [884]

Answer: 76 miles per hour

Step-by-step explanation:

east bound: t = 4, r = x - 18

west bound: t = 4, r = x

d = r * t

680 = 4(x - 18 + x)

680 = 4(2x - 18)

170 = 2x - 18

188 = 2x

94 = x

eastbound: x - 18 = 94 - 18 = 76

Answer:

The separated values of x and y from the given equation is $x=\frac{13-3y}{4}, y=1-\frac{4}{13}x$

Step-by-step explanation:

Given equation is $4 x+3y=13$

Now to find the separated values of x and y with the given equation.

Now find the value of x and so we have to separate the value x from the given equation

$4x+3y=13$

$4x=13=3y$

$x=\frac{13-3y}{4}$

Therfore $x=\frac{13-3y}{4}$

Now find the value of y and so we have to separate the value y from the given equation

$4x+13y=13$

$13y=13-4x$

$y=\frac{13-4x}{13}$

$y=\frac{13}{13}-\frac{4x}{13}$

$y=1-\frac{4}{13}$

Therefore $y=1\frac{4}{13}x$

The separated values of x and y from the given equation is

$x=\frac{13-3y}{4}, y=1-\frac{4}{13}x$
