Answer: No, because when you divide 3/8 you get .375 and when you divide 8/13 you get .62
Not sure where they even got the 5 from.
Puppies : Adults = 1 : 4
Total parts = 1 + 4 = 5
5 parts = 100 dogs
1 part = 100 ÷ 5 = 20 dogs
Answer: 20 puppies
Well you can take out a 7 and y^2 since both have it.
-3y should be your answer because you got rid of 7y^2 and then you have to divide -21/7 to get -3. Also if you take y^2 from y^3 you are left with just a "y".
Answer: The answer is A: (-2,8) and (2,-8)
Step-by-step explanation:
I hope this helps!
'y' is NOT the number of chairs in each row and column. It's the TOTAL number of
chairs, so it's the product of (chairs in each row) times (chairs in each column).
The problem says that those numbers are equal. So we would expect the TOTAL
to be a perfect square, and the number in each row and each column to be the
square root of the total. Since the total is 81, the number in each row and column
could be either +9 or -9 . Both answers are mathematically correct, but -9
doesn't make sense in the real world. So we know that +9 is the real answer.
