Answer:

Z = 4X / Y^2 + 3W

Z - 3W = 4X / Y^2

(Z - 3W) * Y^2 = 4X

1/4 * (Z - 3W) * Y^2 = X

X = 1/4 * (Z - 3W) * Y^2

Subtract $3w$ from both sides:

$z-3w = \dfrac{4x}{y^2}$

Multiply both sides by $y^2$ :

$y^2(z-3w) = 4x$

Divide both sides by 4:

$\dfrac{y^2(z-3w)}{4} = x$

Two trains start from Fort Worth traveling at the same speed. The trip for Train W takes 20 hours, while the trip for Train Z ta

MrMuchimi

Answer:

The equation that best models this situation is :

b. $\frac{x}{20}=\frac{x+400}{25}$

Distance traveled by Train W = 1600 miles

Distance traveled by Train Z = 2,000 miles

Step-by-step explanation:

Given:

Time taken for Train W to complete a trip = 20 hours

Time taken for Train Z to complete a trip = 25 hours

The city Train Z is traveling to is 400 miles farther away than the city Train W is traveling to.

both trains have same speeds and start from same location.

To find the distance in total each train travels.

Solution:

Let length of the trip of Train W be = $x$ miles

Speed of Train W can be given as :

⇒ $\frac{Distance}{Time}$

⇒ $\frac{x}{20}\ miles/h$

So, the length of the trip of Train Z will be = $(x+400)$ miles

Speed of Train Z can be given as :

⇒ $\frac{Distance}{Time}$

⇒ $\frac{x+400}{25}\ miles/h$

Since the speeds are same, so the equation to find $x$ can be given as:

⇒ $\frac{x}{20}=\frac{x+400}{25}$

Solving for $x$

Multiplying both sides by 100 to remove fractions.

⇒ $100\times \frac{x}{20}=100\times \frac{x+400}{25}$

⇒ $5x=4(x+400)$

Using distribution.

⇒ $5x=4x+1600$

Subtracting both sides by $4x$

⇒ $5x-4x=4x-4x+1600$

⇒ $x=1600$

Thus, Distance traveled by Train W = 1600 miles

Distance traveled by Train Z = $1600+400$ = 2,000 miles

Help please !!!!!!!!! thank you

DaniilM [7]

This is an equilateral triangle,
so all sides are equal,
5x-4=3x
2x=2,
x=2
So
|AC|=5x-4=5*2-4=10-4=6
|AC|=6
