A graph of this inequality would be a number line, with the number -2 circled (not filled in), and the number line to the right of -2 shaded.
To solve this, you will combine like terms first:
-3x-7x < 20
-10x < 20
Divide both sides by -10:
-10x/-10 < 20/-10
When you divide an inequality by a negative number, you flip the inequality symbol:
x > -2
I think it is -2288 something like that
Answer:

6. t= 10h + $4.50
Step-by-step explanation:
The final result in dependent on how many hours he uses the boat.
Answer: Choice A
Ahmed started 6 floors above ground level, then he went down 8 floors
The +6 or simply 6, is positive, so he's on the 6th floor to start. Then adding on -8, which is the same as subtracting 8, moves him down 8 floors.
6 + (-8) = 6 - 8 = -2 indicates he's 2 floors below ground level, so he's in basement level 2 (perhaps some kind of parking garage).
