Answer:
We need to know the other marbles in the bag and how many there are of each.
Answer:
x<-3 or x>-1
Step by step explanation:
Start with -5x>15. To get x by itself, we have to divide each side by -5. When we do that we get x<-3. (Don't forget to flip the sign when dealing with negative · and ÷.) Now answer the second equation. x-5>-6 To get x by itself, add 5 to both sides to get x>-1. Now we have x<3 or x>-1.
Answer: 144 cubic feet
Step-by-step explanation:
Volume = base times height.
Base = 20 square feet
Height = 7.2 feet
Volume = 20 square feet * 7.2 feet = 144 cubic feet
3x² + 9x - 54 :(3)
x² + 3x - 18
(x-3)*(x+6)
One year has 12 months therefore...
18/12 = 1 6/12 = 1 1/2
1 1/2 is equivalent to 1.5
True
