Answer:
We conclude that eighty percent of bike tires last at most 14.4 months.
Step-by-step explanation:
We know that a pair of bike tires can last 18 months if used every day.
We calculate how much eighty percent of the tire will last in months.
We have the following proportion:

We conclude that eighty percent of bike tires last at most 14.4 months.
From the first equation
6x - y = 1
6x - y - 1 = 0
6x - 1 = y
Substituting we get
4x - 3(6x - 1) = -11
Answer:
{x,y} = {19/12,5/6}
Step-by-step explanation:
As 1 yard is equal to 3 feet , so 4 yard will be 12 feet !
