Solve the system of equations by substitution - 5x+8y= -86 y=6x-43

n200080 [17]

Answer:

(6 ,-7)

Step-by-step explanation:

$- 5x + 8y = - 86 \\ y = 6x - 43 \\ - 5x = - 86 - 8y \\ x = 17.2 + 1.6y \\ y = 6(17.2 + 1.6y) - 43 \\ y = 103.2 + 9.6y - 43 \\ 8.6y = - 60.2 \\ y = - 7 \\$

$x = 17.2 + 1.6( - 7) \\ x = 17.2 - 11.2 \\ x = 6$

if i want the track to have a circumference of 400 feet what does the diameter of the track need to be?

natta225 [31]

Answer:

The diameter of the track needs to be 127.27 feet

Step-by-step explanation:

* Lets explain how to solve the problem

- The circumference of any circle is C = 2πr, where r is the radius

of the circle and π is the constant ratio between the

circumference and the diameter of the circle which

approximately is 22/7 or 3.14

- The diameter of any circle is twice its radius

* Lets solve the problem

- The circumference of the track is 400 feet

∵ The circumference = 2πr

∵ π = 22/7

∴ 400 = 2 × 22/7 × r

∴ 400 = 44/7 r

- Divide both sides by 44/7 to find r

∴ r = 63.63

∵ The diameter of the circle = 2r

∵ The radius = 63.63 feet

∴ The diameter = 63.63 × 2 = 127.27 feet

* The diameter of the track needs to be 127.27 feet
