Solve. -5/4n = 40

OpenStudy (anonymous):

what is n

TheSmartOne (thesmartone):

Hello there!

OpenStudy (anonymous):

hi

TheSmartOne (thesmartone):

multiply both sides by -4/5 to solve for n :)

OpenStudy (anonymous):

what...

TheSmartOne (thesmartone):

\(\sf\Large -\frac{5}{4} \times -\frac{4}{5} = ?\)

OpenStudy (anonymous):

40 times -5, =200 divide by 4 =-50 n=-50

MsBrains (ms-brains):

That seems pretty simple to solve.

MsBrains (ms-brains):

I got n=-32, How did you get that @SamanthaMarie16

OpenStudy (anonymous):

so its -50?

OpenStudy (anonymous):

or -32

MsBrains (ms-brains):

I think it's -32

TheSmartOne (thesmartone):

let's do it step by step, guys

TheSmartOne (thesmartone):

\(\sf\Large 40 \times -\frac{4}{5} =?\) What is 40 x 4 = ? @goopyfish908

OpenStudy (anonymous):

-5/4n=40 you do the opposite which is -5 times 40 =-200 then you do -200 divided by 4 to get n by its self and it is -50

OpenStudy (anonymous):

160

TheSmartOne (thesmartone):

ok, good job, goopy. Now what is 160/5 = ?

OpenStudy (anonymous):

32

TheSmartOne (thesmartone):

and now we stick on the negative sign, so your final answer is \(\boxed{n=-32}\)

OpenStudy (anonymous):

thank you soo much

TheSmartOne (thesmartone):

anytime! :D
