Answer:
n+12 <4
Step-by-step explanation:
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!

Answer:
0.45
Step-by-step explanation:
Die 1 is loaded so that only 1, 4, and 6 are possible.
P(1) + P(4) + P(6) = 0.5 + 0.25 + 0.25 = 1
Similarly, Die 2 is loaded so that only 2, 3, and 5 are possible.
P(2) + P(3) + P(5) = 1
0.3 + 0.25 + P(5) = 1
P(5) = 0.45
