Question

Which number line represents the solution to the inequality 22 > 10x

Answer 1

`\large\boxed{x<2.2\to x\in(-\infty,\ 2.2)}`

Explanation:

`22>10x\qquad\text{divide both sides by 10}\\\\(22)/(10)>(10x)/(10)\\\\2.2>x\to\boxed{x<2.2}`

<, > - open circle

≤, ≥ - closed circle

<, ≤ - draw the line to the left

>, ≥ - draw the line to the right
