The sum of a number b and 3 is greater than 8 and less than
12
<span>=> b + 3 < 8
=> b + 3 > 12
</span>
<span>Now,
let’s combine this into an expression:
=> 8 < b+3 < 12
=> (8 - 3) < b < (12 - 3)
=> 5 < b < 9
Thus, the answer in the given situation is 9 because 9 is greater than 8 but
less than 12.

Answer:
3.6
Step-by-step explanation:
After the decimal point to the right, the first number is the 'tenths' spot. That number is the one they're asking you to round.

So, the answer is 3.6
