The image is restricted. Can you upload it to here?

OpenStudy (anonymous):

lol, I can't because they required to login

OpenStudy (anonymous):

i will try

OpenStudy (anonymous):

here is the problem

OpenStudy (anonymous):

and then here is the C answer

OpenStudy (tyteen4a03):

When you see + (- something), it means - something. Find the GCD of both fractions and then turn both fractions' denominator to the GCD.

OpenStudy (anonymous):

it'd be 10 right

OpenStudy (anonymous):

its C isnt it

OpenStudy (anonymous):

\[\frac{ 7 }{ 2 }+ \frac{ -3 }{ 5 }= \frac{ 35}{ 10 }- \frac{6}{10}=\frac{29}{10}\]

OpenStudy (anonymous):

oh okay

OpenStudy (anonymous):

@dtran20 I have some more do you think you could help please

OpenStudy (anonymous):

@dtran20

OpenStudy (anonymous):

sure.

OpenStudy (anonymous):

thanks one sec

OpenStudy (anonymous):

3[14 ÷ (42 – 32) – 5] –9 27 21 6

OpenStudy (anonymous):

@dtran20

OpenStudy (anonymous):

im thinking that its -9

OpenStudy (anonymous):

u sure u copy it right?

OpenStudy (anonymous):

the answer is in term of fraction if that's the correct question

OpenStudy (anonymous):

yeah

OpenStudy (anonymous):

\[3[14\div(42-32)-5]=3[14\div(10)-5]=3[\frac{ 14 }{ 10 }-5]=3[\frac{ 7 }{ 5 }-5]=3[-\frac{ 18}{ 5 }]=-\frac{ 54 }{ 5 }\]

OpenStudy (anonymous):

I didn't te last part

OpenStudy (anonymous):

so we have 3(7/5 -5), we can also write as 3(7/5-5/1), lowest common denominator, 3(7/5-25/5), so we have 3(-18/5), then we multiply 3 with -18, we'll have -54/5
