Use f and m for "female" and "male." Then f = m + 16, and f + m = d (total)
So now we have the system of linear equations
f = m + 16
f + m = d
We can eliminate f by subst. m + 16 for f in the second equation:
d-16
m + 16 + m = d, or 2m + 16 = d. Find m. 2m = d - 16, so that m = --------

Assuming that the male horses are either brown or black, and that 25% of these are brown, then the rest must be black. This number is
d-16

Answer:
After 5 minutes Kaitlyn have to mow 5,250 square feet of lawn.
Step-by-step explanation:
We are given the following in the question:
Total area of lawn = 5,625 square feet
Rate of mowing lawn = 75 square feet each minute
Area of lawn mowed in 5 minutes =
Square feet does Kaitlyn still have to mow after 5 minutes
Thus, after 5 minutes Kaitlyn have to mow 5,250 square feet of lawn.
