Solve. 5 + d > 5 – d A. d > 10 B. d > 0 C. d < –5 D. d > –10

alones (alones):

Same as from your last problem you start from simplifying \(d+5>−d+5\) and add \(d\) to each sides \[\ d+5+d>−d+5+d\] \[\ 2d+5>5\]

OpenStudy (iroklas):

So -3d > 5?

alones (alones):

\( -3d>5\) for what?

OpenStudy (iroklas):

idk...

alones (alones):

No when you d \(\ d+5+\color{red}{d}>−d+5+\color{red}{d} \)

alones (alones):

after subtracting it from both sides you should get \( 2d+5>5\)

OpenStudy (iroklas):

Uh huh...

OpenStudy (iroklas):

so d + 3 > 5 is the next step?

alones (alones):

After that you subtract 5 \(\ 2d+\color{red}{5}−5>5−\color{red}{5}\) which would give you \( 2d>0\)

alones (alones):

from there try to divide 2 on each side [\frac{ 2d }{ 2 }\]=\frac{ 0 }{ 2 }\]

alones (alones):

So your final answer would be \(d>0\)
