<span>A) 2x+3y=6
B) 3x-y=2
Multiplying equation B by 3
9x -3y = 6 then adding it to equation A
2x + 3y = 6
11x = 12
x = 12 / 11
</span>
2x + 3y = 6
3y = 6 -2x
y = 2 -(2/3)x
y = 2 -(2/3) * (12/11)
y = 2 -8/11
y = 14 / 11

Therefore, it has one solution

Given a feedlot of about 1200 cows, if an individual cow produces about 50 liters of manure a day, how many liters of manure wou

Amiraneli [1.4K]

Hello!

First you have to find how many liters of manure is made a day

1 cow makes 50 liters a day

We can do 50 * 1200 to find how many liters the cows make a day

50 * 1200 = 60000

Then you multiply this my how many days are in a month

60000 * 30 = 1800000

The answer is 1,800,000 liters of manure a month

Hope this helps!
