[{"id":2035,"question":"Quelle est la solution de l'équation 3x - 5 = 10 ?","option_a":"x = 5","option_b":"x = 15","option_c":"x = 5\/3","option_d":"x = 3","option_e":"","option_f":"","bonne_reponse":"A","explication":"Pour résoudre 3x - 5 = 10, on ajoute 5 des deux côtés : 3x = 15, puis on divise par 3 : x = 5.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":2036,"question":"Quel est le résultat de 2\/3 + 1\/6 ?","option_a":"3\/9","option_b":"5\/6","option_c":"1\/2","option_d":"4\/6","option_e":"","option_f":"","bonne_reponse":"B","explication":"On réduit au même dénominateur : 2\/3 = 4\/6, donc 4\/6 + 1\/6 = 5\/6.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":2037,"question":"Dans un triangle rectangle, si un angle mesure 30°, quel est l'autre angle aigu ?","option_a":"30°","option_b":"60°","option_c":"90°","option_d":"45°","option_e":"","option_f":"","bonne_reponse":"B","explication":"La somme des angles d'un triangle est 180°. Si un angle est 90° et un autre 30°, le troisième mesure 60°.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":2038,"question":"Quelle est la moyenne de la série : 4, 6, 8, 10 ?","option_a":"6","option_b":"7","option_c":"8","option_d":"9","option_e":"","option_f":"","bonne_reponse":"B","explication":"La moyenne se calcule en additionnant les valeurs (4+6+8+10=28) et en divisant par le nombre de valeurs (28\/4=7).","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":2039,"question":"Quelle est l'image de 2 par la fonction f(x) = 3x + 1 ?","option_a":"4","option_b":"5","option_c":"7","option_d":"9","option_e":"","option_f":"","bonne_reponse":"C","explication":"Pour trouver l'image de 2, on remplace x par 2 : f(2) = 3*2 + 1 = 7.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0}]
