If you set up a proportion, this will make sense.
Now, Cross Multiply
6x = 12.5
x = 25/12
Answer: 4.4%
Step-by-step explanation:
Probability of drawing blue first is 6 in 15
Assuming you get that one, the second is 5 in 14 (as you've taken a blue one out)
If that's successful you have 5 in 13 chances of pulling another blue
As you want the first AND second AND third to happen, you multiply them…
(6/15)*(5/14)*(4/13) = 0.04395
So as a percentage, to the nearest tenth is 4.4%
Answer:
Terri is wrong the roots are -4 and 3. She mixed up the numbers
Step-by-step explanation:
Hope it helps mark me brainliest
A rational number can be expressed in the form a/b, where a and b are other integers. To satisfy this definition, 0.9 can be written as 9/10, 18/20, 90/100, etc.
6x-3y=3
-2x+6y=14.
First step is multiply the top equation by 2, so you have
12x-6y=6
-2x+6y=14
-6y and +6y cancel each other out, so if you simplify, you have
10x=20, which is then solved by dividing each side by 10, and getting x=2.
Now plug x=2 into one of the equations (I chose the first)
6(2)-3y=3
12-3y=3
-3y=-9, divide each side by -3 and get y=3.
so your point is (2,3)
