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

Answer:

a) The addition property of equality

b) The division property of equality

Step-by-step explanation:

Here, we want to know the correct step to use

From the given question, to proceed;

All we have to do is to move the value that has a negative value on the left hand side to the right hand side

what accompanies this is the addition of the both terms, on the right hand side

After this, we now proceed to divide the sum by the coefficient of x

Thus, the correct choices are;

a) The addition property of equality

b) The division property of equality
