Answer:
The area of the shaded region is the difference between the areas of the rectangle and the square.
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!


what's the population in 2004? well, from 1994 to 2004 is 10 years later, so t = 10
plug that in, to get P for 2004
Answer:
18.57
Step-by-step explanation:
First you have to simplify the equation using cross-multiplication
You should get 7v=130
Then divide both sides by 7
You should get v=130/7
simplify that and get 18 4/7
Turn that into decimal form and you get 18.57
