Reil [10]

Answer:

Equation  \ of \ the \ line =>  (y -y_{2})  =m(x -x_{2} )

slope, m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} } =\frac{-4-2}{1--2} = \frac{-6}{3} = -2

Equation the line passing through (-2, 2) and ( 1, -4)

(y -- 4) = -2(x -1)\\\\(y +4) = -2x + 2\\\\y = -2x +2 -4 \\\\y = -2x -2

If one worker can lay 10 bricks every hour, and one bandit steals 3 bricks every hour, then how long would it take 8 workers and
erma4kov [3.2K]

It will take 21.53 hours for 8 workers and 5 bandits to lay 1400 bricks.

Given that one worker can lay 10 bricks every hour, and one bandit steals 3 bricks every hour, to determine how long it would take 8 workers and 5 bandits to lay 1400 bricks, the following calculation must be performed:

  • 10 - 3 = 7
  • 5 x 7 + 3 x 10 = X
  • 35 + 30 = X
  • 65 = X
  • 1400/65 = X
  • 21.53 = X

Therefore, it will take 21.53 hours for 8 workers and 5 bandits to lay 1400 bricks.
