Which expression is equivalent to "subtract 5 from 10 then multiply by 4"? 10−5⋅4 4⋅(5−10) 4⋅(10−5) 5−10⋅4 will medal and follow

OpenStudy (wckeller):

If you are subtracting 5 from 10 what order do the numbers need to go in?

OpenStudy (roman):

i missed my class on this

OpenStudy (roman):

they gave me home work of it

OpenStudy (wckeller):

Think about it, 5 FROM 10........ taking away 5 from the number 10

OpenStudy (roman):

i think im retarded

OpenStudy (roman):

5

OpenStudy (wckeller):

No your not!

OpenStudy (wckeller):

And yes the answer of "taking away 5 from 10" is indeed 5

OpenStudy (wckeller):

but the answer choices do not want you to do the operation, just to write it down.

OpenStudy (wckeller):

So, this part of the answer would be (10-5)

OpenStudy (wckeller):

Now for the next part, it says to multiply by 4

OpenStudy (wckeller):

Do you know what the acronym PEMDAS stands for?

OpenStudy (roman):

nope

OpenStudy (roman):

crap

OpenStudy (roman):

i thought you said (10-5) was the awnser

OpenStudy (wckeller):

Okay, P.E.M.D.A.S Parentheses Exponents Multiplication Division Addition Subtraction That is what PEMDAS stands for. This indicates what to do first in a problem. So step one would be to work within the parentheses.

OpenStudy (roman):

told you im retared

OpenStudy (wckeller):

No i said that that was the answer to the first PART of the question.

OpenStudy (roman):

im so dumb lol

OpenStudy (roman):

dude im about to post another qustion i will medal you if you come help

OpenStudy (wckeller):

Because we do not have any exponents in the problem, we can move on to multiplication. Remember that you are doing (10-5) FIRST. This means that whatever comes after it has to be outside the parentheses. So multiply (10-5) and 4

OpenStudy (wckeller):

Final answer= 4*(10-5)

OpenStudy (wckeller):

Ill help

OpenStudy (roman):

awesome thats the awnser i said
