Train A and train B leave a central station at the same time. They travel the same speed, but in opposite directions, with train

mash [69]

Speed = distance / time
since they are moving in opposite direction, the time is the sum of the two times = 2 1/2 + 4 = 6 1/2 = 13/2

speed = 585/(13/2) = 90 miles per hour.

I need to know the answer to 5n-2=3n+40

andrew11 [14]

Hey there!

$5n -2$ $= 3n +40$
Firstly, let's $subtract$ by the number $3n$ on both of your sides
$5n -2-3n$ $= 3n + 40 - 3n$
We get: $= 2n - 2 = 40$
Nextly, let's $add$ by the number $2$ on each of your sides
$2n - 2+2$ $= 40 +2$
$40 +2$ $=42$
We get: $2n$ $=42$
Thirdly, $divide$ by $2$ on each of your side
$\frac{2n}{2}$ $=$ $\frac{42}2}$
Cancel: $\frac{2n}{2}$
Keep: $\frac{42}{2}$ because it gives you your overall answer
$\boxed{Answer: n = 21}$

Good luck on your assignment and enjoy your day!
