Answer:
100 miles
Step-by-step explanation:
Relative Speed: 60+40=100 mph
you can think that one train is stationary,another one is 100 mph
so one hour before the train pass each other,the distance is 100 miles
Answer:
Step-by-step explanation:
In the first triangle, using Pythagorean's theorem, x^2+3^2=5^2, x = 4
In the second triangle, using Pythagorean's theorem, x^2+7^2=24^2, x = 25
In the third triangle, using Pythagorean's theorem, 8^2+15^2=x^2, x = 17
In the fourth triangle, using Pythagorean's theorem, x^2+8^2=10^2, x = 6
In the fifth triangle, using Pythagorean's theorem, 5^2+12^2=x^2, x = 13
You need to have more evidence for us to answer this question
Distribute 6(x+4) = 8(x-2)
6x+24 = 8x-16 subtract by on both sides
-24. -24
6x = 8x-40 subtract by on both sides
-6x. -6x
2x = -40
divide both by 2 on each side
and X=20
