2x + 50 > = 100 (thats greater then or equal)

2x > = 100 - 50

2x > = 50

x > = 50/2

x > = 25

minimum number is 25

Answer:the mass of the air inside the inflated balloon is 4 grams

Step-by-step explanation:

The initial mass of the balloon before it was inflated by the Math and Science class is 4 grams. After the balloon was inflated, the mass was 8 grams. This means that the mass by which the balloon increased would be the mass of the inflated balloon - the initial mass of the balloon. It becomes

8 - 4 = 4 grams.

Therefore, the mass of the air inside the inflated balloon is 4 grams.
