Answer: the two trains will meet in 2.8 hours
Step-by-step explanation:
Step 1
Speed of train A = 90mph
Speed of train B = 110 mph
Since both trains are travelling towards each other
, their effective speed will be= 90 mph + 110mph= 200mph
Step 2
we know that Speed = distance / time
therefore Time = Distance / speed
Distance = 560 miles
Speed = 200 mph
Time = 560miles / 200mph
2.8 hours
Simple....
you have:
5x+2=4x-9
5x+2=4x-9
-4x -4x
x+2=-9
x+2=-9
-2 -2
x=-11
Thus, your answer.
2) confucianism ( there are several similarities between confucianism and buddhism so I think confucianism is right answer)
It is easily b because you have to subtract the demensions and you get 8 squared
