Answer:57 = x

Step-by-step explanation:

Using the proportion given, there will be 57 catfish in the pond.

The proportion given to us is

5.7/20 = x/200

Cross multiply:

5.7*200 = 20*x

1140 = 20x

Divide both sides by 20:

1140/20 = 20x/20

57 = x

6.<br> What is the midpoint of the line segment whose<br> endpoints (7,-4) and (-3, -2)?<br> are
quester [9]

Answer: (2, -3)

Step-by-step explanation:

To find the the answer, you will need to use the midpoint formula, which is as following:

(x₁+x₂/2, y₁+y₂/2)

Since we have two coordinates, let's substitute them into the equation.

(7 + (-3 )/ 2, (-4) + (-2)/2)

We should first add 7 and -3 together, as well as -4 and -2.

(4/2, -6/2)

We then divide 4 and -6 by 2. This would give us our midpoint coordinate.

(2, -3)
