Let the number be x. 2*(x +4) < 12
2x+8 < 12 2x < 12-8 2x < 4 Divide both sides by 2.
x < 4/2 x< 2. Therefore the number is less than 2.

The **value **of x is less than 2.
What is inequality?
**Inequalities **are the mathematical expressions in which both sides are not equal . The solution to an equation or inequality is any number that, when plugged into the equation or inequality , will satisfy the **equation **or inequality .
**Inequalities **are expressed using greater than, greater than or equal to, less than, or less than or equal to.
For the given situation,
The **expression **is 2(x+4) < 12
⇒ 2 x + 8 < 12
⇒ 2 x < 12 − 8
⇒ 2 x < 4
⇒ x < 2
Hence we can conclude that the **value **of x is less than 2.

The inequality representing the statement 'Twice the sum of a number and 4 is less than 12' is 2 ( x + 4 ) < 12 . Simplifying it leads to x < 2 .

1. A dan ClKemungkinan "A" di sini adalah Aluminium (Al) dan "ci" adalah Klorin (Cl)➡️ Senyawa: Aluminium Klorida➡️ Rumus: AlCl₃➡️ Penjelasan: Al (golongan 3A) membentuk ion Al³⁺, Cl membentuk ion Cl⁻ → maka butuh 3 Cl⁻ untuk menetralkan 1 Al³⁺2. Na dan O➡️ Senyawa: Natrium Oksida➡️ Rumus: Na₂O➡️ Penjelasan: Na⁺ dan O²⁻ → 2 Na⁺ diperlukan untuk menetralkan 1 O²⁻3. K dan S➡️ Senyawa: Kalium Sulfida➡️ Rumus: K₂S➡️ Penjelasan: K⁺ dan S²⁻ → 2 K⁺ diperlukan untuk menetralkan 1 S²⁻4. Be dan I➡️ Senyawa: Berilium Iodida➡️ Rumus: BeI₂➡️ Penjelasan: Be²⁺ dan I⁻ → 1 Be²⁺ butuh 2 I⁻ untuk menetralkan5. Ca dan O➡️ Senyawa: Kalsium Oksida➡️ Rumus: CaO➡️ Penjelasan: Ca²⁺ dan O²⁻ → rasio 1:1 karena muatan sama besar dan berlawanan
