Using the given equation and edge length:
V = 45^3
V = 45 x 45 x 45
V = 91,125 cubic meters
Answer:
C. 1
Step-by-step explanation:
Use the first one since it is -4 so
You would solve this with simultaneous equations, so if we write it as:
5n + 2p = 9
3n + 2p = 6
(subtract)
2n = 3
÷ 2
notebooks = 1.5
Now you would substitute it in:
(3 × 1.5) + 2p = 6
4.5 + 2p = 6
- 4.5
2p = 1.5
÷ 2
pens = 0.75
So your final answer is notebooks are $1.50 and pens are $0.75, I hope this helps!
