Step-by-step explanation:
Number of cows increased=60
Old quality of milk consumed=12.8litres
New Increase in milk consumed=15litres
Therefore the number of cows in the farm if the quality of milk is 1340litres=y
Therefore, 1cow =15litres
y cows= 1340litres
Crossmultiply:
15litres×ycows=1340litres
Make y the subject of formula
y= 1340÷15
y=89.33cows
Therefore,the number of cows on the farm if farmer gets 1340litres of milk would be 89cows.

Answer:
Step-by-step explanation:
Let total money be m
Then, the money spent on 2 video games is 1/5m
<u>Each game costs:</u>
So each video game costs 1/10 of birthday money
X=-33 y= 10
Leave first row the same multiply 2nd row by -1
-2x+8y=14
2x+2y=26
10y= 40
Y=4
-2x+8(10)=14
-2x+80=14
