Calculators buddy calculators ;) 77 / (-11) = -7

OpenStudy (anonymous):

77/(-11)= -7 no real explaining can be done

OpenStudy (anonymous):

OpenStudy (anonymous):

for –7.2 ÷ –0.9=8

OpenStudy (anonymous):

ok is it - or +

OpenStudy (anonymous):

+

OpenStudy (anonymous):

Yes -7.2 divided by -0.9 = positive (+) 8

OpenStudy (anonymous):

ok and 24 ÷ (–8 – (–4))

OpenStudy (anonymous):

no 2 sorry

OpenStudy (anonymous):

24 divided by (-8 - (-4)) = -6 but if you meant 24 being 2 then it would be -0.5

OpenStudy (anonymous):

but there is now decimals in the answers

OpenStudy (anonymous):

so its -6

OpenStudy (anonymous):

ok and What is the value of the expression \[\frac{ z-4 }{ -8 }\] when z = –28?

OpenStudy (anonymous):

after this is the last one

OpenStudy (anonymous):

just plug in -28 for z

OpenStudy (anonymous):

so it is -28?

OpenStudy (anonymous):

no...plug in -28 for z like...................-28-4/-8
