Answer:
20 animals = x chickens (2 legs) + y horses (4 legs).
x+y=20 (total number of animals)
2x+4y=64 *total number of legs)
x+y=20
x+2y=32
If you solve this system of animal with 2 and 4 legs, you get 6 chickens and 14 horses
x=6
y=14

Answer:
I’m sorry but I don’t understand the question
Step-by-step explanation:
To make the equation equal y
x=(y-5)^2
√x=√(y-5)^2
√x=y-5
this is because the 'root' cancels the 'square root'
√x=y-5
√x+5=y
<span>Each Exterior Angle = (360 degrees) ÷ (Number of Sides)
</span>
A pentagon has 5 sides so
<span>Each Exterior Angle = 360 / 5
</span>
Each Exterior Angle =72
If the exterior angle = 2x and the angle = 72 degrees then
2x = 72 and
x = 36
