Answer: number of adults = 3, number of children = 5
Step-by-step explanation:
let the number of adults be x, and the number of children be y.
x + y = 8 , 15x + 8y = 85
1st equation x 8 = 8x + 8y = 64
![8x+8y-15x-8y = 64 - 85\\-7x = -21\\x=3](https://tex.z-dn.net/?f=8x%2B8y-15x-8y%20%3D%2064%20-%2085%5C%5C-7x%20%3D%20-21%5C%5Cx%3D3)
substitute x=3
![3+y=8\\y=5](https://tex.z-dn.net/?f=3%2By%3D8%5C%5Cy%3D5)

12/4
The top number always goes inside (larger or not), and the bottom number always goes on the outside (larger or not).
______
4 | 12
Ask yourself how many 4's are in 12.
Let's see one 4 is just 4.
We can probably do more 4's than that.
Two 4's gives us 4+4=8.
Let's see if we can put one 4 in there.
Three 4's gives us 4+4+4=12.
So we can fit three 4's into 12 and there is nothing left over.

4 | 12

Answer:
.79 mm^2
Step-by-step explanation:
First find the area of the circle
A = pi r^2
A = 3.14 (1) ^2
A = 3.14
Now we have 1/4 of the circle
The area is 1/4 of the full area
1/4 *3.14
.785
Rounding to the nearest hundredth
.79 mm^2
