Answer:
x=3; y=3
Step-by-step explanation:
y = -1/2 x + 9/2
so if we multiply by 2 on both sides
2y = -x + 9
and we know that y = 3x-6
so we get
2(3x-6)=-x+9
6x-12 = - x + 9
7x = 21
x = 3
y = 3 * 3 - 6
y=3

x=3, y=3
You put them in the equation and they should work.

Answer:
Yes.
Step-by-step explanation:
Since there is an overlap, that does mean some people with brown hair do wear watches, but not all of them do. Hence it's independent.
There's 16 hours from 11 am to 3 am
16 times .75= 12 hours
11 am add 12 hours is 12 am midnight
You have 18 rainy out of 90 total. You need to simplify each term.
18 = 1, 2, 3, 6, 9, 18
90 = 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
Now find the largest number that is common. That would be 18. Divide both numbers by 18
18/18 = 1
90/18 = 5
So the simplified ration is 1/5
