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.

the answer for this question is 38

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.
