At a pond there were 24 ducks swimming. the ratio of duckling to adult ducks is 5 to 1. how many ducklings were swimming at the pond.

Twenty ducklings were swimming at the pond

Step-by-step explanation:

Let

x> the number of ducklings

y> the number of adult ducks

we know that

x+y=24 > equation A

\frac{x}{y}=\frac{5}{1}

so

x=5y

y=0.20x > equation B

Substitute equation B in equation A

x+0.20x=24

1.20x=24

x=20 ducklings

answer: 8d

step-by-step explanation:

45+5= 50+5=55+5=60

c) the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

town a, median = q2 = 30

town b, median - q2 = 25

so the median for town a 30" is greater than the median for town b 25"
