Answer:
the answer is 900
Step-by-step explanation:
the 900 will not be necessary
For one it would be c and d
Two x is greater than seven
three would be x is greater than or equal to 6
Four would be subtract eight from both sides you get 24 and then divide by negative four which gets you negative six but then you have to turn the sign around. Number set would be anything above negative six,so like negative five, 52, and one
Five would be subtract 3 from both sides giving you 5 on the right side and then multiply by six on both sides giving you thirty on the right side, resulting in x is greater than or equal to thirty. Three numbers that would work would be thirty, fifty nine, and thirty five.

Answer:
A line a and line b
Step-by-step explanation:
Lines b and c are parallel (no intersection points), so the system will have no solutions.
Lines b and d are parallel (no intersection points), so the system will have no solutions.
Lines c and d coincide (infinitely many intersection points), so the system will have infinitely many solutions.
Lines a and b will intersect after extension, so the system of these two equations will have only one solution.
Density=mass/volume.
1) we have to calculate the iron volume in liters.
iron volume=second level - first level=49.10 ml-45.50 ml=3.6 ml
3.6 ml=3.6 ml(1 liter / 1000 ml)=0.0036 liters
2) we calculate the mass iron in kg.
28.5 g=28.5 g(1 kg /1000 g)=0.0285 kg.
2) we calculate the density of iron.
density=0.0285 kg / 0.0036 liters=7.92 kg/L
7.92 kg/l=7.92 kg/L(1000 g/1Kg)(1000 cm³/1 L)=7.92 g/cm³.
answer: From this information the Iron density is 7.92 Kg/L or 7.92 g/cm³.
