Answer:
B. (b+3c)+(b+3c)
C. 2(b)+2(3c)
Step-by-step explanation:
we have
![2(b+3c)](https://tex.z-dn.net/?f=2%28b%2B3c%29)
Distribute the number 2
![2(b+3c)=2b+2(3c)=2b+6c](https://tex.z-dn.net/?f=2%28b%2B3c%29%3D2b%2B2%283c%29%3D2b%2B6c)
Verify each case
case A) 3(b+2c)
distribute the number 3
![3(b+2c)=3b+3(2c)=3b+6c](https://tex.z-dn.net/?f=3%28b%2B2c%29%3D3b%2B3%282c%29%3D3b%2B6c)
![3b+6c \neq 2b+6c](https://tex.z-dn.net/?f=3b%2B6c%20%5Cneq%202b%2B6c)
therefore
Choice A is not equivalent to the given expression
case B) (b+3c)+(b+3c)
Combine like terms
![b+3c)+(b+3c)=(b+b)=(3c+3c)=2b+6c](https://tex.z-dn.net/?f=b%2B3c%29%2B%28b%2B3c%29%3D%28b%2Bb%29%3D%283c%2B3c%29%3D2b%2B6c)
![2b+6c= 2b+6c](https://tex.z-dn.net/?f=2b%2B6c%3D%202b%2B6c)
therefore
Choice B is equivalent to the given expression
case C) 2(b)+2(3c)
Multiply both terns by 2
![2(b)+2(3c)=2b+6c](https://tex.z-dn.net/?f=2%28b%29%2B2%283c%29%3D2b%2B6c)
![2b+6c= 2b+6c](https://tex.z-dn.net/?f=2b%2B6c%3D%202b%2B6c)
therefore
Choice C is equivalent to the given expression
Answer:
1/4
Step-by-step explanation:
coins have 2 sides, tails and heads, so for it to land on tails is a 1/2 chance. Dice have 6 sides and 1,3,5 are all odd so its a 3/6 chance. Simplify 3/6 to 1/2 and multiply by 1/2 to get 1/4. im not sure, its my guess.
I think the answer is 1:2.8 this means there is one snail to every three animals
