7. You are finding the area of the box. Not the cube, just a surface. Length times width of the surface. Eliminate other numbers and multiply
24.5×19.5
then
26×24.5
8. You are doing the same thing almost. Word problems are scary, but look for the numbers.
4inch ×8inch × 12inch
Find the volume
Multiply the volume by 3, that'd one answer
Devide the ORIGINAL volume by 2. don't divide the volume you multiplied by 3.
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.
Here is a key that showed up online
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.
