Answer:Add 44 liters blue
Step-by-step explanation:Mary has 20 liters of paint mixed white:blue in the ratio 2:3. So two fifths of that paint is white and three fifths is blue. So that's 8 liters white, 12 liters blue.
We want to add paint to get white:blue = 1:7. Clearly we need to add blue. We have our 8 liters of white, so we need a total of 7(8)=56 liters of blue. We already have 12, so we have to add 56-12=44 liters of blue paint:
It’s 6
since it’s right at 5 & 7
The slope is 6 and the y-intercept is -8
56x² - 49x + 14 = 7(8x² - 7x +2)
_____
The greatest common factor of 56, 49, and 14 is 7.
112 / 4 = 28
28 x 3 = 84
There are 84:112 men to women working for the company.
