A farmer had twice as many cows as sheep. After he had sold
375 cows and another 12 cows died, he had half as many cows
as sheep left. How many cows remained?

Respuesta :

aorta122307
Answer- 129 cows
Explanation:
C=2S
Now, with C-375-12, then
2(C-375-12)=S

Put the first equation into the second..

2(C-375-12)=C/2
1.5C=2*(387)
C=4/3*387= 4*129=516 and S=258

Now in the end, number of cows=
516-375-12= 129 and S=258
