Answer:
27 chickens
Step-by-step explanation:
A chicken farmer also has cows for a total of 30 animals
Both animals have a total of 66 legs
Let a represent the number of chicken
Let b represent the number of cows
a + b= 30........equation 1
Since a chicken has only two legs and a cow has four leg then, the expression can be represented as
2a + 4b= 66........equation 2
From equation 1
a + b= 30
a = 30-b
Substitute 30-b for a in equation 2
2a + 4b= 66
2(30-b) + 4b= 66
60 - 2b + 4b= 66
60 + 2b= 66
2b= 66-60
2b= 6
b= 6/2
b= 3
Substitute 3 for b in equation 1
a + b = 30
a + 3=30
a= 30-3
a= 27
Hence the farmer has 27 chickens
Answer:
No, these triangles cannot lie on the same line.
Step-by-step explanation:
Step-by-step explanation: For two triangles to lie on the same line they must have the same slope. slopes are negative because the triangles are leaning to the left.

Answer:
2754
Step-by-step explanation:
Given,
Length = 18 yards is equivalent to 54 feet
Width = 51 feet
So area of the field = Length * width
= 54 x 51
=2754 square feet
