Answer:
1/2
Step-by-step explanation:
We only care about the third coin
we could get heads or tails on the third flip
P (third coin will be heads) = outcome heads / total
=1/2
M=30/22,5=1,33
m=25/x=1,33. ...>x=25/1,33=18,7
An=a1+(n-1)×d
1+(n-1)×5
1+5n-5
An= 5n-4
Answer:
3 minutes
Step-by-step explanation:
Let's say that the bathtub is 15L
It would take 7.5 mins to fill 15L
15L/7.5 = 2L per minute
The other tap would take 5 minutes to fill 15L
15L/5 = 3L per minute
3L per minute + 2L per minute = 5L per minute
15L/5L per min = 3 minutes

Put all that information into an inequality and you get:
4x + 8y ≥ 50
