Answer:
Number of ducks = 37
Number of pigs = 18
Step-by-step explanation:
Let,
x be the number of ducks
y be the number of pigs
According to given statement;
x+y=55 Eqn 1
2x+4y=146 Eqn 2 (As ducks will have 2 legs and pigs will have 4)
Multiplying Eqn 1 by 2
2(x+y=55)
2x+2y=110 Eqn 3
Subtracting Eqn 3 from Eqn 2
(2x+4y)-(2x+2y)=146-110
2x+4y-2x-2y=36
2y=36
Dividing both sides by 2

Putting y=18 in Eqn 1
x+18=55
x = 55-18
x = 37
Hence,
Number of ducks = 37
Number of pigs = 18
Answer:
18
Step-by-step explanation:
<u>Product</u> is another word for multiplication, and 2 * 9 = 18.

Answer:
110 degrees
Step-by-step explanation:
I don't know if that is correct.
Can you post this and provide a picture please so I can help you ?
Explanation:
Well not sure what you are asking, but If it is what I think it is, it would go like this:
2
(9^2)
Then the answer should be
9^4 since we multiply the exponents.
If you mean this...
3^2....It would be same as 3 x 3 which we should know is equal to nine.
Hope I helped! (Be sure to thank me!)
