6 greater than b is
[tex]=b+6[/tex]6 greater than b is greater than 84. is represented as
[tex]b+6>84[/tex]Step :Subtract 6 from both sides
[tex]\begin{gathered} b+6>84 \\ b+6-6>84-6 \\ b>78 \\ \end{gathered}[/tex]Therefore,
[tex]\begin{bmatrix}\mathrm{Solution\colon}\: & \: b>78\: \\ \: \mathrm{Interval\: Notation\colon} & \: \mleft(78,\: \infty\: \mright)\end{bmatrix}[/tex]Hence,
The interval notation is (78,∞)
