Hey the solution to your question is (5,10).
Answer:
$130.68
Step-by-step explanation:
1 acre = 43,560 square feet
3/4 of 43560 = 32,670 (So that would be 76,230 sq ft in 1.75 acres because 43560 + 32670 = 76230)
We need to divide the total by 35 plots.
76230 / 35 = 2178, using long division.
2,178 square feet is just one plot of 35. We need to multiply 2178 by 0.06.

Answer: 15 goats
Step-by-step explanation:
h = hens - they have 2 legs
g = goats - they have 4 legs
The equations would be:
h + g = 19
2h + 4g = 68
To solve this, I personally prefer substitution, we're isolating h since we need to find g:
h + g = 19
h = 19 - g
Now that we have h, we can plug this into the second equation:
2h + 4g = 68
2(19 - g) + 4g = 68
38 - 2g + 4g = 68
2g = 30
g = 15
There are 15 goats.
Adding onto this, 19 - 15 = 4, so there are 4 hens.
Given that h=(1/5)w+(8/5), which is a straight line equation that takes the form y=ax+b, where a is the slope and b is the y-intercept. The equation has infinite number of solutions. The solutions are in the interval (-∞,∞).
The answer: Infinite soltuions
