Answer:
2x²y⁴
Step-by-step explanation:
Area = W × L
W = A / L = 
= 2x²y⁴
No, because if they were equal the second equation should be 225/(15x3), not (15/3).
Answer:
Step-by-step explanation:
u put the gs with each other by flipping the one that was changed
3.6g-1.6g=8-2
2g=6
g=6/2
g=3
It would be: 63 / 28 = 9 / 4
So, your answer is 9/4
Hope it helped.
Let's define variables:
s = original speed
s + 12 = faster speed
The time for the half of the route is:
60 / s
The time for the second half of the route is:
60 / (s + 12)
The equation for the time of the trip is:
60 / s + 60 / (s + 12) + 1/6 = 120 / s
Where,
1/6: held up for 10 minutes (in hours).
Rewriting the equation we have:
6s (60) + s (s + 12) = 60 * 6 (s + 12)
360s + s ^ 2 + 12s = 360s + 4320
s ^ 2 + 12s = 4320
s ^ 2 + 12s - 4320 = 0
We factor the equation:
(s + 72) (s-60) = 0
We take the positive root so that the problem makes physical sense.
s = 60 Km / h
Answer:
The original speed of the train before it was held up is:
s = 60 Km / h
