Answer:
An additional amount of blue is: 44 liters
Step-by-step explanation:
We can solve this problem in the two steps:
First we will make proportion
w : b = 2 : 3 => w = 2 c and b = 3 c where c is coefficient of proportion
We know that we have a total of 20 l of paint, which mean>
w + b = 20 => 2 c + 3 c = 20 => 5 c = 20 => c = 20/5 = 4 => c = 4
w = 2 c = 2 · 4 = 8 liters
b = 3 · 4 = 12 liters
Now we will make second proportion:
w : (b + x) = 8 : (12 + x) = 1 : 7
When we multiply external and internal members we get:
12 + x = 8 · 7 => 12 + x = 56 => x = 56 - 12 = 44 liters
x = 44 liters
God with you!!!
The dependent variable is the one on the left side of the equal sign (y).
The independent variable is the one on the right side of the equal sign (x).
