In a team bike race, each biker has to ride exactly 50 miles. the team must complete 560 miles. how many miles must each biker travel?

12 bikers are required.

Step-by-step explanation:

Each Biker has to ride 50 miles

Let number of bikers be  x

so total travel by x bikers = 50 multiplied by x = 50x

According to the question

  50x = 560

Dividing both sides by 50 ,we get

x = 11.2

Since number of bikers cannot be in in decimals

therefore  it is 12

12 bikers are required.

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
