Answer:
1:2
Step-by-step explanation:
There are 12 total puppies. To find the number of black puppies, we have to subtract the yellow from the total. So:
12 - 8 = 4
There are 4 black puppies. Now we put the black puppies in ratio to yellow puppies:
4:8
Then simplify (divide both sides by 4):
1:2
Answer:
16 friends
Step-by-step explanation:
Right at the beginning, you can take the 2 chocolates Jack was left with out of the 50 chocolates Jack had at the beginning. That equals 48 chocolate bars, so we know that Jack gave his friends a total if 48 chocolates

Now that you have the number 48, you are really close to the answer.
If you know that he gave each if his friends 3 chocolates, you can make that into an equation and put it into a calculator. That would look like this:

The reason you do 48 ÷ 3 is because Jack divided his 48 chocolates into groups of 3 to give to each of the other kids.
You get the answer 16, which means the answer is 16 kids at his friend's birthday party.
f(x) = 3x + 5/x
f(a + 2) = 3.(a + 2) + 5/(a + 2)
Alternative C.
The answer is 160/3 I think
