The width in inches would be 12, because of the formula:
length x width = perimeter
so you would do it reverse!
perimeter/length = width
so, 144/12 = 12

3y=12x
y=4x
the constant is 4 which answers your question
Answer: There are 40 cars and 5 motorcycles at the end of buying and selling. He started with 9 motorcycles and 36 cars.
Step-by-step explanation:
x=# of motorcycles 4x=# of cars
8(x-4)=4x+4
8x-32=4x+4
4x=36
x=9
---
4(9)+4=36+4=40
9-4=5
The correct answer would be B, or the second option.
In a function like this, the y-intercept, or the term without a variable, can be always be interpreted as a sort of starting amount, or a base amount.
Because we're given 5x + 20, we know 20 will be the base, or starting value, while 5 is the amount being added per value of x, which is equal to weeks.
Thus, the correct answer is B.
