Answer:

Step-by-step explanation:
The way I like to think about it, with absolute value meaning the distance is
"find which number are 16 apart from 12". Which means 28 (to the right) or -4 (to the left).
More formally, applying the definition of absolute value,

X in litres is 67% herbicide
y in litres is 46% herbicide
{x+y=42
{0.67x+0.46y=42*0.55
{67x+46y=2310
{46x+46y=1932
21x=378
x=18 litres
A. She need to use 18L
The value of x is 35 degrees, as it is opposite to the other 35 degree angle. Now, to find y. We can see by the indicators that the measure of the y angles are equal. These angles, along with the 35 degree angle that is indicated are in a straight angle. This helps us. Form an equation.
2y+35=180
2y+35-35=180-35
2y=145
y=72.5
Therefore, the value of the x angle is 35 degrees and the value of the y angle is 72.5 degrees.
Hope this helps.
Answer:
24
Step-by-step explanation:
50 L X 3 = 150 L (water value for horses)
4 L X 15 = 60 L (water value for sheep)
200 mL X 12 = 2,400 mL or 2.4 L (water value for chickens)
Add them all together.
150 + 60 + 2.4 = 212.4 L of water is used daily
