Answer:
Step-by-step explanation:
Take what's given and write an equation. If you know that the distance to the mid point is half of the entire length, you can say
2(x+6) = 9x -2
Distribute to get 2x + 12 = 9x -2
Solve 12 +2 = 9x -2
7x = 14. So x=2
Substitute 2 for x in the original equation.
2(2+6) = 9(2) - 2
16 = 16
So the length of UW is 16

Answer: 1/6
Reason:
There's 1 side labeled "4" out of 6 sides total. So that's where the 1/6 comes from.
The "given that you already rolled a four on the first die" is unneeded info in my opinion, because each die is separate or independent from one another.
8y = -6
Simply add the equations as you would numbers.
The 'x's cancel each other out. The 'y's add together as normal numbers.
9 + (-15) = -6
Hope that this helps!
