Answer:
1) 240 cows.
2) 80 cows.
3) 8 days.
Step-by-step explanation:
1) To find the number of cows that could be fed for 4 days, you need to substitute [tex]x=4[/tex] into the equation, then:
[tex]y=\frac{960}{x}\\\\y=\frac{960}{4}\\\\y=240[/tex]
2) To find the number of cows that could be fed for 12 days, you need to substitute [tex]x=12[/tex] into the equation, then:
[tex]y=\frac{960}{x}\\\\y=\frac{960}{12}\\\\y=80[/tex]
3) Farmer Bill has two feed his 85 cows and 35 cows of his neighbors, then the total number of cows he needs to feed is:
[tex]y=85+35\\y=120[/tex]
Substitute this value into the equation and solve for "x" to find the number of days he could feed them:
[tex]120=\frac{960}{x}\\\\120x=960\\\\x=\frac{960}{120}\\\\x=8[/tex]
