An airplane travels 2836 km against the wind in 4 hours and 3156 km with the wind in the same amount of time. What is the rate o

PilotLPTM [1.2K]

Answer:

with wind velocity = 3156/4 = 789 mph

against wind velocity = 2836/4 = 709 mph

(789/709) / 2 = 40 mph

wind velocity = 40 mph

plane velocity = 789 - 40 = 749 mph

What is the solution to 7.5d=2.5d

Vikki [24]

Answer:

d = 0

Step-by-step explanation:

To find the solution to the given equation, we must solve for d in the equation.

7.5d = 2.5d

Subtract 2.5d from both sides.

5d = 0

Divide both sides by 5.

d = 0

So the solution to the equation would be d = 0.

I hope this helps. Happy studying.

How do I find the value of k so that the line (2+k)x + (2-k)=15 has slope 3/2

nataly862011 [7]

The value of k must be:

$\boxed{k=\frac{2}{5}}$

<h2>Explanation:</h2>

$(2+k)x+(2-k)y=15$

First of all, you need to know that the Slope-intercept form of the equation of a line is given by:

$y=mx+b \\ \\ m:Slope \\ \\ b:y-intercept$

So, let's arrange our given equation:

$(2+k)x+(2-k)y=15 \\ \\ (2-k)y=-(2+k)x+15 \\ \\ y=\frac{2+k}{2-k}x+\frac{15}{2-k}$

As you can see, we can know that:

$m=\frac{2+k}{2-k} \\ \\ b=\frac{15}{2-k}$

But we know that the slope is 3/2:

$\frac{2+k}{2-k} =\frac{3}{2} \\ \\ Solving \ for k: \\ \\ 2(2+k)=3(2-k) \\ \\ 4+2k=6-3k \\ \\ 2k+3k=6-4 \\ \\ 5k=2 \\ \\ k=\frac{2}{5}$
