Answer:

$\mathrm{No\:Solution}$

Step-by-step explanation:

By using comparing the left hand side of the two given equations we have:

The sum of three consecutive even integers is 36. Let x represent the first integer, x + 2 represent the second integer, and x +

nikitadnepr [17]

To start this, try to place it all together.

(x)+(x+2)+(x+4)=36

Then you start to combine so that it looks like this:

3x+6=36

Answer:

5 seconds

Step-by-step explanation:

Suppose the front parts of the trains meet at point A. Since both are the same length and traveling the same speed, each will pass point A in time ...

time = distance/speed

time = (1/18 mi)/(40 mi/h) = (1/720 h) × (3600 s)/(1 h) = 5 s

That is, the rear part of each train will be at point A 5 seconds after the front part.

The rear parts will pass each other 5 seconds after the front parts meet.
