12.

Start of with simply two times six, which is twelve. Since they're both negatives, they cancel each other out and become positive.

Hope this helps!

Hey there! :)

-2 · (-6)

Let's remember that a negative times a negative is always a positive!

So, because both of our numbers are negatives, we know that our outcome should be positive.

Because we know our answer is a positive, we can simply remove the negatives to make it easier for us to understand.

2 · (6)

Remove our parenthesis.

2 · 6 = 12

Therefore, our answer is 12!

To solve this problem you must apply the proccedure shown below:

1. You must make a system of equation by using the information given in the problem above. Then, let's call:

x: The number of computers sold.

y: The number of hard drives sold.

2. Therefore, you have the following system of equations:

\left \{ {{x+y=36} \atop {1180x+125y=30875}} \right.

2. Solve for x in the first equation and substitute it into the second equation:

x=36-y\\ 1180(36-y)+125y=30875

3. Solve for y:

42480-1180y+125y=30875\\ y=11

4. Substitute the value of y into the first equation to calculate x:

x+11=36\\ x=25

Therefore, the answer is: The store sold 25 computers and 11 hard drives.
