Answer:
22.5 grams of 10% cream is mixed with 37.5 grams of 2 % cream to prepare 60 grams of 5% cream.
Step-by-step explanation:
Let x grams of 10% cream is mixed with y grams of 2 % cream to prepare 60 grams of 5% cream.
So, x + y = 60 ............ (1) and

⇒ 10x + 2y = 300
⇒ 5x + y = 150 ............ (2)
Now, solving equations (1) and (2) we get,
4x = 150 - 60 = 90
⇒ x = 22.5 grams
So, y = 60 - x = 37.5 grams. (Answer)
Donc pour trouver la réduction de 30% nous allons trouver 30% de 49 alors nous allons faire 30 × 100 × 49 = 14,7 14,7 est la réduction maintenant nous devons faire 49 € -14,7 € soit 34,3 €, le prix est maintenant de 34,3 €, désolé d'utiliser Google Translate pour vous aider, mais j'espère que c'est correct :)

Take into account the the Earths gravity is 9.8 meters a second
116/9 = 12.88
713/9 = 79.22
495/9 = 55
640/9 = 71.11
360/9 = 40
it would be 495 and 360
