Answer

$\left[ \dfrac{7}{2}, -\infty\right)$

Work Step by Step

Using $a(b+c)=ab+ac$ (or the Distributive Property), and using the properties of inequality, the solution to the given expression, $ 5(x-2)\ge3(x-1) ,$ is \begin{array}{l}\require{cancel} 5x-10\ge3x-3 \\\\ 5x-3x\ge-3+10 \\\\ 2x\ge7 \\\\ x\ge\dfrac{7}{2} .\end{array} Hence, the solution is $ \left[ \dfrac{7}{2}, -\infty\right) .$
