Look at the picture below
The answer is:
3×3×5×7×7 or
3²×5×7²
You can do 144 times 1/8, which is the same thing as <span>144÷8.
The answer is 18.</span>
I'm going to assume that they are on parallel tracks, and not the same track.
60x=40(x+2)
60x=40x+80
20x=80
x=4
You can check the work I've provided by filling in the answer for x into the initial question.

P/8=14/3
P=14*8/3
P=37.3333
Here, I'll help you a little
rewrite the equation as -6k/5 = 12
multiply both sides by 5
-6k=60
divide both sides by -6 to isolate k
k = -10
Hope this helps :)
