Answer: -3x -19y +8
Explanation:
we have two expressions 17x -13y +8
and 20x +6y
difference = 17x -13y +8 -(20x+6y) (1)
Now, when we open the bracket and there is a negative sign before it sign inside the bracket gets changed above equation (1) will be written as
17x - 13y +8 - 20x -6y
Now, we can simplify the above expression we will get
-3x - 19y +8

We know that the mixture has 14 mm of ink. Of these, 35% are blue pigment, hence the mixture contains 4.9 mm of blue ink. Ink A contains 10%*4mm=0.4mm of blue ink. The difference, 4.5 mm of blue ink must have come from ink B. Thus ink B contains 4.5 mm of blue ink and is in total 10mm. After that, we can calculate the percentage; we divide 4.5/10=0.45 and this is the ratio of blue ink to total ink (in Ink B). If we transform it to percentages it is 45%
