Answer:
The farmer has 4 cows and 15 chickens.
Step-by-step explanation:
This question can be solved using a system of equations.
I am going to say that:
x is the number of cows
y is the number of chickens.
A farmer has a total of 21 cows and chickens altogether
This means that x + y = 21.
The animals have 54 legs
A cow has four legs, while a chicken has 2 legs. So
4x + 2y = 54.
From the first equation:
y = 21 - x
Replacing
4x + 2(21 - x) = 54
4x + 42 - 2x = 54
2x = 12
x = 6
y = 21 - x = 21 - 6 = 15
The farmer has 4 cows and 15 chickens.
25:63=25/63=0.39682539682=0.40=40%

The two ways to write the expression k/3+16 are 1/3k + 16 and (k + 48)/3
<h3>How to rewrite the expression?</h3>
From the question, the expression is given as
k/3+16
Start by factoring 1/3 out of the first term
So, we have the following expression
1/3k + 16
The above is one of the ways of rewriting the expression
Another way is by taking the LCM
So,we have
k/3+16 = (k + 48)/3
Hence, the equivalent expressions are 1/3k + 16 and (k + 48)/3
