Answer:
Ducks = 8
Horses = 17
Step-by-step explanation:
From the question;
- Total number of animals = 25
- Total number of legs = 84 legs
We are required to determine the number of ducks and horses;
We need to know that;
A duck has two legs while a horse has four legs;
Assuming there were x ducks and y horses
Then;
x + y = 25 ................................Eqn 1
And;
2x + 4y = 84 .............................Eqn 2
Solving the two equations simultaneously we can get the number of each animal.
x + y = 25
2x + 4y = 84
Multiplying the first equation by 2, we get
2x + 2y = 50
2x + 4y = 84
Subtracting the two equations;
2x + 2y = 50
2x + 4y = 84
........................................................
- 2y = -34
y = 17
Solving for x
x = 25 -17
= 8
Therefore; there were 8 ducks and 17 horses in the field

Answer:
After those four plays, the Raptors gained 37 yards from the first play.
Step-by-step explanation:
Since the Raptors football team was losing when they got control of the ball at midfield in the last minute of a game, and they lost 25 yards on the first play they ran, but then they gained 5 yards on the second play, while on the third play, the Raptors gained 27 yards, and on the fourth play, they gained 30 yards, to determine what was the position of the ball relative to its starting point after those four plays the following calculation must be performed:
0 - 25 + 5 + 27 + 30 = X
-25 + 5 + 27 + 30 = X
-20 + 27 + 30 = X
7 + 30 = X
37 = X
Therefore, after those four plays, the Raptors gained 37 yards from the first play.
The first one would have a credit score of 600 and the second one has a score of 760
