Unit rate is like miles per hour. If John walks 500 miles in 5 hours, the unit rate is 500/5=100 miles per hour.
4x+1=6x-2
4x+3=6
3=2x
3/2=2x/2, because you have to divide 2 from both sides
X=3/2
He would make $1239.75
divide 4 in 2,204
multiply by 2.25
<u>Answer:</u>
There are 243 ducks in the preserve.
<u>Explanation:</u>
Given:
In a wildlife preserve, 45 ducks are captured, tagged, and released.
Later, 200 ducks are examined, and two of them are tagged.
To Find:
To estimate how many ducks are in the preserve =?
Solution:
Now, we know that, out of 200 2 ducks are tagged, which means remaining 198 ducks are untagged.
Now, total ducks count = ducks with tags + ducks with out tag
Total ducks count = 45 + 198
Total ducks count = 243
Hence, there are 243 ducks in total.
