824 is the answer because you add
To solve this question, let's find the surface area of the entire pie and then divide it by 6 for each slice.
The area of a circle is pi*r^2. We are given the diameter, so divide that by 2 to get the radius.
Now that you have the area, divide by 6. That is the area of each slice. The problem asks for the area of 2 slices though, so multiply that by 2.
Answer:
see below
Step-by-step explanation:
![x^{\frac{p}{r}}=\sqrt[r]{x^{p}}](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7Bp%7D%7Br%7D%7D%3D%5Csqrt%5Br%5D%7Bx%5E%7Bp%7D%7D)
![3a^\frac{5}{3} =\sqrt[3]{3a^5}](https://tex.z-dn.net/?f=3a%5E%5Cfrac%7B5%7D%7B3%7D%20%3D%5Csqrt%5B3%5D%7B3a%5E5%7D)
There are 12 white ribbons, 15 red ribbons, and 11 blue ribbons.
38=(w-1)+(w+3)+w
combine like terms
38=2+3w
subtract 2 from both sides
36=3w
divide 3 on both sides
12=w
w-1=b
12-1=b
11=b
w+3=r
12+3=r
15=r

w+r+b=38
15+11+12=38
38=38
