$$\mathrm{The}\mathrm{length}\mathrm{of}\mathrm{the}\mathrm{interval}\mathrm{of}\mathrm{solution}$$$$\mathrm{a}⩽2\mathrm{x}+5⩽\mathrm{b}\mathrm{is}15.\mathrm{What}\mathrm{is}\mathrm{b}-\mathrm{a}?$$

Answered by Aziztisffola last updated on 29/Aug/20

$$\frac{\mathrm{a}-5}{2}⩽\mathrm{x}⩽\frac{\mathrm{b}-5}{2}$$$$\frac{\mathrm{b}-5-\mathrm{a}+5}{2}=15\Rightarrow \mathrm{b}-\mathrm{a}=30$$
