1) B=-12

2) 189.69

Step-by-step explanation:

Explanation 1: To find B, we have to replace the given points in the equation, that is , x=2 and y=1

$3x+By+6=0\\3.2+B.1+6=0$

Then we solve for B.

$6+B+6=0\\B+12=0\\B=-12\\$

Hence , B=-12

explanation 2: you have the following equation for the number of liters 3% milk:

0.03+0.1(200)-x=0.05(200)

Solve the previous equation for x:

0.03x+20-x=10

$0.03-x=10-20\\-0.97x=-10\\x=10.31$

Hence , there are 10.31 liters of 3% milk

Add the numbers of liters 10% butterfat is :

200-10.31=189.69 liters
