Answer:

Step-by-step explanation:
The given equation is 
Differentiate both sides with respect to x

Take y and 1 to other sides of the equation

Factor out dy/dx from the left hand side of the equation

Divide both sides by (x+1)

5/18 ÷ 2/6
5/18 * 6/2
30/36
5/6
X= 4.5
18x - 9 = 72 are the equations
Could depend on many things, but i believe it would be ounce.
The product would be 200 obliviously it would be miles because it says five months so it’s implying that you need to find the amount biked in 5 months
So it’s should be miles
