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.
Answer:
x = 3
Step-by-step explanation:
y =4x - 2
4 x 3 = 12
Answer:
$0.86, or 86 cents
Step-by-step explanation:
5 = $ 4.30
1 = $ 0.86
$4.30/5 = $0.86, or 86 cents per pound.
Just combine these.
3x + 3x = 6x
x = 6
y = 1
