slavikrds [6]

Answer:

15 sheep

Step-by-step explanation:

1 leg = 1 foot

1 head = 1 animal

Suppose all the animals are chickens:

50 × 2 = 100

130 - 100 = 30

4 - 2 = 2

30 ÷ 2 = 15

Hence, there are 15 sheep.

Gnesinka [82]

Answer: There are 97 nickels and 108 quarters.

Step-by-step explanation:

Let x = Number of nickels, y = Number of quarters.

As per given,

x+y = 205    ...(i)

0.05x+0.25y = 31.85 ... (ii)    [1 nickel = $0.05, 1 quarter = $ 0.25]

Multiply (ii) by 20, we get

x+5y=637   ...(iii)

Eliminate (i) from (iii)

4y = 432

⇒ y = 108 [Divide both sides by 4]

Put value of y in (i), we get

108+x=205\Rightarrow\ x= 97

Hence, there are 97 nickels and 108 quarters.
