Answer:
1) x=4-y-z
2) x=-12+4y-4z/3
3) x=-1+y+4z/2
Step-by-step explanation:
1) Subtract y+z from both sides.
x+y+z-(y+z)=4-(y+z)
Simplify
x=4-y-z
2) Subtract -4y+4z from both sides.
-4y+4z-(-4y+4z)=12-(-4y+4z)
Simplify
-3x=12+4y-4z
Divide both sides by -3
-3x/-3=12/-3+4y/-3-4z/-3
x=-12+4y-4z/3
3) Subtract -y-4z from both sides.
2x-y-4z-(-y-4z)=-1-(-y-4z)
Simplify
2x=-1+y+4z
Divide both sides by 2
2x/2=-1/2+y/2+4z/2
Simplify
x=-1+y+4z/2

This will give Seth the value of 0.24 to the black marble and 0.16 to the red marble. So if Seth will choose that can make him correct, he should choose the one who has higher probability that will help him. So between the two values, Seth should choose the black marble which is 8 points higher than the red marble.

Answer:
m + n = 26 and n = 2m + 5
m = 7, n = 19
Step-by-step explanation:
Because we know that the sum of m and n is 26, we get the first equation. For the second equation, we are told that n is five more than twice m. So we multiple m by 2 and then add 5 to that to get what n is. This is our second equation.
We plug the second equation in for n in the first equation to get
m + (2m + 5) = 26
3m + 5 = 26
3m = 21
m = 7
And then for n, we solve the first equation to get
7 + n = 26
n = 19
Answer: A nut in botany is a simple dry fruit in which the ovary wall becomes increasingly hard as it matures, and where the seed remains unattached or free within the ovary wall. Most nuts come from the pistils with inferior ovaries (see flower) and all are indehiscent (not opening at maturity).
