sorry didn't mean to cut you off, what did you get?
OpenStudy (bekkah323):
i got -9 and it told me it was -13/45
jimthompson5910 (jim_thompson5910):
is there more to it? I don't see any fractions in the problem
OpenStudy (bekkah323):
sorry i was looking at the wrong answer? this one didn't have an answer, but im still not sure if i did it right
jimthompson5910 (jim_thompson5910):
and the problem is (8-7)-9 ? and nothing else?

if so, then
(8-7)-9
(1)-9
1 - 9
-8
so (8-7)-9 = -8
jimthompson5910 (jim_thompson5910):
oh nvm it's different
jimthompson5910 (jim_thompson5910):
so in 10-6^2/9^2+3^2 only the 9^2 is under the 6^2 right?
jimthompson5910 (jim_thompson5910):
it will probably be best to draw it out
OpenStudy (bekkah323):
Yah i screwed this whole question up, sorry!

Or use parenthesis.
jimthompson5910 (jim_thompson5910):

OpenStudy (bekkah323):
yah i can draw it out
jimthompson5910 (jim_thompson5910):
thanks

thanks that helps

\[\large \frac{ 10-6^2 }{ 9^2+3^2}\]
\[\large \frac{ 10-36 }{ 81+9}\]
\[\large \frac{ -26 }{ 90}\]
\[\large \frac{ 2(-13) }{ 2(45)}\]
\[\large \frac{ -13 }{ 45}\]
\[\large -\frac{ 13 }{ 45}\]
So
\[\large \frac{ 10-6^2 }{ 9^2+3^2} = -\frac{ 13 }{ 45}\]
OpenStudy (bekkah323):
ok thanks that makes sense!
jimthompson5910 (jim_thompson5910):
that's great, yw
