Question 32: Let x be a value satisfying \( {\sqrt {2,25} .x + 2.\left( {0,5x – \sqrt {\frac{{121}}{9}} } \right ) = \frac{{11}}{3}}\). Select the correct answers.





\(\begin{array}{*{20}{l}} {\sqrt {2,25} .x + 2.\left( {0.5x – \sqrt {\frac{{121}}{9} } } \right) = \frac{{11}}{3}}\\ {1.5x + 2.\left( {0.5x – \frac{{11}}{3}} \right) = \ frac{{11}}{3}}\\ {1.5x + 2,0.5x – 2.\frac{{11}}{3} = \frac{{11}}{3}}\\ {1, 5x + x – \frac{{22}}{3} = \frac{{11}}{3}}\\ {x\left( {1.5 + 1} \right) = \frac{{11} }{3} + \frac{{22}}{3}}\\ {2,5x = \frac{{33}}{3}}\\ {2,5x = 11}\\ {x = 11: 2.5}\\ {x = 4.4} \end{array}\)
