Answer:
243, 729
Step-by-step explanation:
the last number given in the sequence is multiplied by 3
against wind the speed = x-y
distance traveled = 2460
2460/x-y= 6
6x-6y= 2460
x-y=410...........1
..
with wind speed = x+y
distance is same 2460
2460/x+y=5
5x+5y=2460
x+y=492............2
..
Add equation 1 & 2
x-y+x+y=410+492
2x=902
x= 451 mph speed of plane in still air.
..
Plug the value of x in equation 1
451-y=410
y=451-410
y=40 mph the speed of wind

Answer:
where is the question
Step-by-step explanation:
send question
Because there are 18 socks, 18 is the denominator, and there are 3 blue so blues the numerator. So the chance of getting a blue sock is 3/18 chance. I hope this helps.
