I have a screenshot of the answer
<h3>Answer:</h3>
room 3 or 4
<h3>Explanation:</h3>
We assume the inequalities tell the rooms that were checked and found empty.
The solution to 3) is ...
... 2x + 3 > 11
... 2x > 8 . . . . . subtract 3
... x > 4 . . . . . . .divide by 2
The solution to 4) is ...
... -3x > -9
... x < 3 . . . . . . divide by -3
Thus, rooms greater than 4 and less than 3 were found empty. Rooms 3 and 4 were not checked, so either one could hold Nessie.
_____
The other inequalities have solutions that are already covered by the solutions to these.
1) x < -1 . . . . after subtacting 4
2) x > 5 . . . . after multiplying by 5
The answer would be $3 becaus of x = $12 and y = $9. $12 - $9 = $3.
1. 18,000 x 1.03 (3% increase) either type 1.03 into your calculator 25 times or use an exponent ↓↓↓↓↓↓↓
18000 x 1.03^25 (25 years past) =37,688.00
