Answer:There are 72 heads (chicken and rabbit) and 200 legs. How many chickens and rabbits are present totally?
Step-by-step explanation
There are 72 heads (chicken and rabbit) and 200 legs. How many chickens and rabbits are present totally?
Legs of a chicken = 2
Legs of a rabbit = 4
Total heads = 72
Total legs= 200
Let's assume that each of them has minimum 2 legs.
So 72*2 = 144 legs
Remaining legs: 200-144= 56
These remaining legs belong to rabbit because rabbit has 4 legs each.
2*Rabbits= 56
Rabbits= 56/2 = 28
Out of 72, 28 are rabbits. So there are 72-28= 44 chicken.
Answer:
11.74b + 72.16
Step-by-step explanation:
In this question, we're going to simplify the expression.
Solve:
1.9b + 8.2(8.8 + 1.2b)
Use the distributive property.
1.9b + 72.16 + 9.84b
Combine like terms.
11.74b + 72.16
Since we can't simplify any further, 11.74b + 72.16 would be your answer.
1.63 is the answer. :))))))
