Question

Solve the inequality.

4d + 7 ≤ 23

Answer 1

`Solution, 4d+7\le \:23\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:d\le \:4\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:4]\end{bmatrix}`

`Steps:`

`4d+7\le \:23`

`\mathrm{Subtract\:}7\mathrm{\:from\:both\:sides},\\4d+7-7\le \:23-7`

`\mathrm{Simplify},\\4d\le \:16`

`\mathrm{Divide\:both\:sides\:by\:}4,\\(4d)/(4)\le (16)/(4)`

`\mathrm{Simplify},\\d\le \:4`

`\mathrm{The\:Correct\:Answer\:is\:d\le \:4}`
