8.2(-6.5)=?

OpenStudy (anonymous):

what does it means? is it to multiple all number?

OpenStudy (anonymous):

i think so i'm not sure there are no instructions sorry

OpenStudy (anonymous):

so, you have \[8\times2\left( -6 \times5\right)\] because, all is about multiplying you just multiple all number, nothing to worry

OpenStudy (anonymous):

but, beware of negative number in multiplying happy to help... :D

OpenStudy (anonymous):

none of the answers i have match those, thank you so much though

OpenStudy (hihi67):

Okay, I think I can help. It would be 8.2 times negative 6.5 right?

OpenStudy (perl):

here http://lmgtfy.com/?q=8.2*(-6.5)

OpenStudy (anonymous):

okay i have the answers if that'd help?

OpenStudy (perl):

http://lmgtfy.com/?q=8.2*(-6.5)

OpenStudy (hihi67):

That is -53.3

OpenStudy (phi):

8.2(-6.5) means multiply 8.2 times -6.5 you have a + times a negative, so the answer will be negative 8.2 time 6.5 is the same as 82 times 65, but in the answer you adjust the decimal point to have 2 numbers to the right of the decimal point.

OpenStudy (hihi67):

@sadaholic19 is that one of the options?

OpenStudy (perl):

http://lmgtfy.com/?q=8.2*(-6.5)

OpenStudy (anonymous):
