Answer:
60 percent
Step-by-step explanation:
6 black socks, 4 white socks, 10 socks altogether, 60 percent of the socks are black, so is the chance of picking both black socks
A good place to start is to set 
to y. That would mean we are looking for 
to be an integer. Clearly, 
, because if y were greater the part under the radical would be a negative, making the radical an imaginary number, not an integer. Also note that since 
is a radical, it only outputs values from ![[0,\infty]](https://tex.z-dn.net/?f=%20%5B0%2C%5Cinfty%5D%20)
, which means y is on the closed interval: ![[0,120]](https://tex.z-dn.net/?f=%20%5B0%2C120%5D%20)
.
With that, we don't really have to consider y anymore, since we know the interval that is on.
Now, we don't even have to find the x values. Note that only 11 perfect squares lie on the interval , which means there are at most 11 numbers that x can be which make the radical an integer. All of the perfect squares are easily constructed. We can say that if k is an arbitrary integer between 0 and 11 then:
Which is strictly positive so we know for sure that all 11 numbers on the closed interval will yield a valid x that makes the radical an integer.
I’m not to sure because the picture is blurry
2a + 2c - 5b - c - b
2a + c - 5b - b
2a - 6b + c
8 would become the whole number, since there are 3 repeating numbers you would put those over 999.
So you would get 8 and 132/999
