Answer:
Bridge = 300 m
Speed = 10 m/s
Step-by-step explanation:
If a goes past you in 10 seconds, it means the train has speed of
100 m/ 10 seconds as it is 100 m long
<u>The speed in m/s is:</u>
Then it take 3 times of 10 seconds to cross the bridge, so
<u>The length of the bridge is:</u>
Step-by-step explanation:

Answer:
x=1
y=2
Explanation:
first start with assigning a random value to a variable
lets say x=1
from there the equation becomes solveable
-6x1+7y=8
simplify
-6+7y=8
+6 to both sides
7y=14
divide both sides by 7
y=2
from here we can say that x=1, y=2, can satisfy the equation-6x+7y=8
hope this helps :)
