Answer:
![w=63](https://tex.z-dn.net/?f=w%3D63)
Step-by-step explanation:
the equation to solve this is : ![(w-8)+(2x-1)=180](https://tex.z-dn.net/?f=%28w-8%29%2B%282x-1%29%3D180)
combine the first side of the equation so you get ![3w-9](https://tex.z-dn.net/?f=3w-9)
then add 9 on both sides
divide 3 by 189 which gets you 63.
plug 63 into the equation to double check
hope this helps! :))
Answer:
P(draw a blue or red marble) = ![\frac{16}{21}](https://tex.z-dn.net/?f=%5Cfrac%7B16%7D%7B21%7D)
Step-by-step explanation:
The bag contains 8 blue, 5 green, and 8 red marbles
Total number of marbles is 8 + 5 + 8 = 21
P(draw a blue or red marble) = P(blue marble) or P(red marble)
In probability,"Or" means addition (+)
So, P(draw a blue or red marble) = P(blue marble) + P(red marble)
P(draw a blue or red marble) =
+
= ![\frac{16}{21}](https://tex.z-dn.net/?f=%5Cfrac%7B16%7D%7B21%7D)
P(draw a blue or red marble) = ![\frac{16}{21}](https://tex.z-dn.net/?f=%5Cfrac%7B16%7D%7B21%7D)
The definition of rational is the ability to represent it as a fraction. You have a fraction with 1/7, so it is rational.
