Question

12 ≤ 4n < 28

SOLVE THE COMPOUND INEQUALITY​

Answer 1

`\sf \: 12 ≤ 4n < 28`

• Divide all parts by 4

`\sf \longmapsto (12)/(4)≤ (4n)/(4) < (28)/(4)`

`\sf \longmapsto3≤n<7`

Result:

`\boxed{ \sf 3 \leqslant n<7}`

• Number line attached

Answer 2

`▪▪▪▪▪▪▪▪▪▪▪▪▪  {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪`

`\boxed{ \boxed{3 \leqslant n < 7}}`

The equivalent expression is ~

`\large \boxed{ \mathfrak{Step\:\: By\:\:Step\:\:Explanation}}`

Let's solve ~

• 
  `12 \leqslant 4n < 28`

Now divide each term with 4

• 
  `12 / 4 \leqslant 4n / 4 < 28 / 4`

• 
  `3 \leqslant n < 7`
