Total number of puppies = 12
Where;
Poodles = 3
Terriers = 5
Retrievers = 4
After Rebecca selects a poodle, total number of puppies remaining = 12 -1 =11
Then,
Probability of Aaron selecting a retriever:
P(R) = Number of retrievers/New total = 4/11
5
40/8 is 5. You can check this by multiplying 8 and 5 and seeing if it equals 40. Also, if you look at 40/8 as a fraction you can simplify it. 40/8=20/4=10/2=5/1=5
For 1 multiply both sides by 3 which gives you 3y-y=12. Then combine like terms 2y=12. Lastly divide both sides by 2 and you get y=6. And for 3 first multiply both sides by 4 which gives you 6y-32=y+8. After that combine like terms 6y-y-32=8. Now add the equation together 5y=40 and then divide by 5 and get y=8
The answer would be 71.45
