Question

Solve the inequality. Write the inequality in interval​ notation.
9(t-2)>3(t-7)

Answer 1

`\large\boxed{t>(1)/(2)\to t\in\left((1)/(2),\ \infty\right)}`

Explanation:

`9(t-2)>3(t-7)\qquad\text{use distributive property}\\\\(9)(t)+(9)(-2)>(3)(t)+(3)(-7)\\\\9t-18>3t-21\qquad\text{add 18 to both sides}\\\\9t>3t-3\qquad\text{subtract 3t from both sides}\\\\6t>3\qquad\text{divide both sides by 6}\\\\t>(3)/(6)\\\\t>(1)/(2)`
