Answer:

Working memory

Step-by-step explanation:

Working memory is a system the brain uses  for temporarily storing and managing the information required to carry out complex cognitive tasks. The central executive part of the prefrontal cortex at the front of the brain is responsible for working memory. It serves as a temporary store for short-term memory, where information is kept available while it is needed for current reasoning processes.

So to be successful in holding the number 2.82 in my head while sorting, one must keep the information maintained in short-term storage by using one's working memory.

What property would you use first to solve 1/2x-6=10
NISA [10]

I don't know what you mean by property. Do you mean like, commutative, distributive, etc?

but, if this is what you mean:

to solve this:

The operation here is subtraction. Do the inverse. So, add 6 to both sides of the equation

10 + 6 = 16

1/2x - 6 + 6 = 1/2x. (the 6 cancels out)

1/2x = 16

Now, I'm going to assume 1/2 is supposed to be a fraction (not division). So, 1/2 is right next to x which represents multiplication, so do the opposite which is division.

16 divided by 1/2 = 32

1/2x divided by 1/2 = x

x = 32.
