Réponse :

soit  x : le nombre d'année

on écrit l'équation suivante :  41 + x = 3(11 + x)  ⇔ 41 + x = 33 + 3 x

⇔ 41 - 33 = 3 x  - x  ⇔ 8 = 2 x  ⇔ x = 8/2 = 4

Donc dans 4 ans le père aura le triple de l'âge de son fils

A quiz has multiple-choice questions, each with 5 choices. The answer possibilities are distributed evenly. If a student gets a correct answer they will receive +3 points. If they leave it blank, they will receive 0 points. If they write an incorrect answer, they will receive -1 point. A student guesses the answers to some questions. Determine on average, in the long run, how many points the student will score. (Write your answer as a decimal, with a minus sign if needed.) a0 points per questio
