Step-by-step explanation:
So,
If you are rounding to the nearest tenth of a MB, then it would look like this:
3.2 + 4.9 = 8.1 MB
Because in 3.15, 5 is greater than or equal to 5, and in 4.89, 9 is greater than or equal to 5.
If you are rounding to the nearest MB, then it would look like this:
3 + 5 = 8 MB
Because in 3.15, 1 is less than 5, and in 4.89, 8 is greater than or equal to 5.
In my opinion, I would mentally add them to get 8.14 MB, because if you do math well, you can mentally add these things like second nature. This is really helpful when you go shopping, which I'll bet you will be doing profusely.
(2x) + 11 < 44
x is multiplied by two because we are looking for twice of x. 11 is added to the 2x because we are looking for eleven more than the sum of twice of x. Since 2x + 11 is less than 44, we use the lesser than ( < ) symbol.
Answer:

Step-by-step explanation:
1)
Because it has a half-life of 25 days, half of it will decay after 25 days.
After 
days, there will be 
of it left.
So, 
.
2)
Because it has a half-life of 25 days, half of it will decay after 25 days.
After 
days, there will be 
of it left.
So, 
3)
Because it has a half-life of 25 days, half of it will decay after 25 days.
After 
days, there will be 
of it left.
So, 
.
4)
The only answer left is 
grams. You can solve it the same way you solved the previous steps.
