Answer:
x=5
Step-by-step explanation:
So how i came about to get this answer, was
y=15-3x
y=15-3(5)
y=15-15
y=0
I found five by testing out different numbers for x such as 1 2 3 4, but when i got to five, that was where i got the answer, as shown above.

Answer: B. X<12
Step-by-step explanation:
First we need to find out what number multipled by 4 is less than 56
4 x 12 = 48
56-48 = 8
And 4 is lower/less than 12 so that's why it's B
Stanley the skunk will save about 15.5 feet.
This problem can be solve with the Pythagorean Theorem. The possible paths that Stanley can take make a right triangle. The legs of the triangle are 25 and 28, and the hypotenuse would be 37.5.
If Stanley went the long way, he would travel 25 + 28 = 53 feet. Taking the short way (hypotenuse) is 53 - 37.5 = 15.5 feet shorter.
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!
