Answer:
4 baby blue paints
Step-by-step explanation:
Given
Let b represents blue paint and w, white paints
---for 1 paint
Required
The number of paints in ![20 : 8](https://tex.z-dn.net/?f=20%20%3A%208)
To do this, we set the following equivalent ratios
![5n:2n = 20 : 8](https://tex.z-dn.net/?f=5n%3A2n%20%3D%2020%20%3A%208)
Where n represents the number of paints
By comparison
![5n = 20](https://tex.z-dn.net/?f=5n%20%3D%2020)
![2n = 8](https://tex.z-dn.net/?f=2n%20%3D%208)
Solve for n in both cases;
![5n = 20](https://tex.z-dn.net/?f=5n%20%3D%2020)
![n = \frac{20}{5}](https://tex.z-dn.net/?f=n%20%3D%20%5Cfrac%7B20%7D%7B5%7D)
![n = 4](https://tex.z-dn.net/?f=n%20%3D%204)
![2n = 8](https://tex.z-dn.net/?f=2n%20%3D%208)
![n = \frac{8}{2}](https://tex.z-dn.net/?f=n%20%3D%20%5Cfrac%7B8%7D%7B2%7D)
![n = 4](https://tex.z-dn.net/?f=n%20%3D%204)
The overlap in the two data sets is low
Answer:
27 coaches, 162 divided by 6 equals 27.
You need to find 2 numbers x and y that solve the equations:
x * y = 35
x + y = 12
it looks like x = 5 and y = 7 will work
2x - y = 7
y = 2x - 7 this line has slope = 2
Perpendicular lines, slope is opposite and reciprocal so slope = -1/2
Answer
A . -1/2
