Answer:

B

Step-by-step explanation:

Let the nickels = x

Let the dimes = y

You don't know the total value of either. Nor do you know the total number of either.

You only know the total value of both together.

7.80 added to anything makes it bigger than 7.80 A is wrong.

y cannot be alone it should be multiplied by 0.5    C is wrong

D is wrong for the same reason A is

B is the correct answer. That is the way you write the problem

Number of Coins and value on one side. Total on the other.

Lamar is solving the equation x2−12x=−6 by completing the square. Which shows Lamar's next step and the solution to the equation
Lyrx [107]

x2 - 12x = -6

Your next step would be to add 36 to both sides.

x2 - 12x + 36 = 30

In completing the square, we divide the term before x by 2, and then square it and add it to both sides.

12 / 2 = 6

6^2 = 36

That would be the next step.
