Bonjour, Voici l'énoncé:
Un article de 25€ subit une augmentation de 10% puis une réduction de 20%.
Quel est le taux global d'évolution?
J'espère que vous pourrez me venir en aide :)

Determine the number of outcomes in the event. decide whether the event is a simple event or not. upper a computer is used to select randomly a number between 1 and 9 comma inclusive. event upper b is selecting a number greater than 4. event upper b has nothing outcome(s). is the event a simple event? (yes or no) because event upper b has (fewer than, exactly, more than) one outcome.

What is the solution to this system of equations? y= 2x - 3.5 x - 2y = -14

Type the correct answer in the box. use numerals instead of words. if necessary, use / for the fraction bar.
