HI!!

OpenStudy (misty1212):

is it \[\huge 8a+6(2b-7)\]

OpenStudy (anonymous):

I think it's 54 frfr.....

OpenStudy (misty1212):

\[8\times 5+6(2\times 3-7)\] is what you need to compute

OpenStudy (anonymous):

i thoght it was 33 or 90

OpenStudy (misty1212):

it is not 54 through

OpenStudy (misty1212):

lets take it step by step first we multiply inside the parentheses what is \(2\times 3\)?

OpenStudy (anonymous):

6

OpenStudy (misty1212):

ok so now we have \[8\times 5+6(6-7)\] what is \(6-7\)?

OpenStudy (anonymous):

1

OpenStudy (misty1212):

hmmm er no

OpenStudy (misty1212):

\[7-6=1\] but \[6-7\neq 1\]

OpenStudy (anonymous):

oops i ment to put this -1

OpenStudy (misty1212):

ok so now we are at \[8\times 5+6\times (-1)\]

OpenStudy (misty1212):

multiply next

OpenStudy (anonymous):

8 X 5 = 24

OpenStudy (misty1212):

???

OpenStudy (anonymous):

opps that is wrong

OpenStudy (misty1212):

yeah i think so too

OpenStudy (anonymous):

i ment 40

OpenStudy (anonymous):

sorry my keys have been acting up lately

OpenStudy (misty1212):

k we we are at \[40+6\times(-1)\]

OpenStudy (anonymous):

6 X (-1) = -6

OpenStudy (misty1212):

ok good, and \[40-6=?\]

OpenStudy (anonymous):

34

OpenStudy (misty1212):

bingo \[\color\magenta\heartsuit\]

OpenStudy (anonymous):

OpenStudy (anonymous):
