<span>Chicken have 2 legs. Rabbits have 4 legs. Let the number of chicken be x and the number of rabbits be y. Then we have the following equations: x + y = 72 (the total number of animals in the cage) and 2x + 4y = 200 (the total number of legs in the cage). In the first equation we express x relative to y and get that x = 72 - y. Then we replace it in the second equation and get 2*(72 - y) + 4y = 200 <=> 144 + 2y = 200 <=> y = 56/2 <=> y = 28. And since x = 72 - y we get that x = 44. So in total we have 44 chicken and 28 rabbits.</span>
Answer:
wx+10=20 20-10 =10
Step-by-step explanation:
because wx=? when the side change of any equation sign is change
Area of circle = πr²
Given that area = 153.86 m², find the radius:
153.86 = πr²
r² = 153.86 ÷ π
r² = 48.98
r = √48.98
r = 7 m
Diameter = Radius x 2 = 7 x 2 = 14 m
Answer: Diameter = 14 m
