If you distribute -5 to the things in the parenthesis you would get 10k-20 which is the same as -5(-2k+4)
Answer:
-2/5
Step-by-step explanation:
TOTAL NO.OF ANIMALS IN FARMHOUSE=42
RATIO OF COW : BUFFALO=5:9
LET THE NO.OF COWS BE 5X AND BUFFALOES BE 9X
5X + 9X =42
14X=42
X = 42/14
X= 3
TOTAL NO.OF COWS = 5 x 3 =15
TOTAL NO.OF BUFFALOES = 9 x 3 = 27
