Answer:

The wheels have to rotate 500 times

Step-by-step explanation:

The wheel is 1 meter in diameter so we need to find the circumference.

C = 2\pir

C = 2\pi1

C= 2\pi

2meters = .002kilometers

1000meters = 1kilometer

1000/2 = 500

If 5x - 3y = 1 and x = 2y - 4, then x • y = ?
Inessa05 [86]

Answer:

x = 2,  y = 3

Step-by-step explanation:

i) It is given that 5x - 3y =1

ii) It is also given that x = 2y - 4

iii) we can substitute the value of x from ii) in the equation in i) and we will get 5(2y - 4) - 3y = 1   ⇒ 10y - 20 -3y =  1   ⇒  7y = 21  ∴ y = 3

iv) substituting the value of y obtained in ii) we get x = (2 × 3) - 4 = 6 - 4 = 2.

v) Therefore x = 2.
