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.

Step-by-step explanation:
Option 4 2x + y = - 4 is the correct answer
Combine terms. 13x-6x = 7x. 10y-(-7y)=17y
So it’s 12x+17y
68000. The reason this is the answer is because you have to move the decimal point to the right 3 times since it’s x3
Answer:
Step-by-step explanation:
When interest compounds once per year, the formula for this is
where P is the initial investment, r is the interest rate at which it grows, and t is the time in years. Therefore, our model is
