200 + 10x = 120 + 15x now solve the equation to find x, the number of hours that both companies will charge the same ammount

torisob [31]

Answer:

Step-by-step explanation:

Given the equation, $200 + 10x = 120 + 15x$ , let's solve for x as follows,

Subtract 200 from both sides

$200 + 10x - 200 = 120 + 15x - 200$

$10x = - 80 + 15x$

Subtract 15x from both sides

$10x - 15x = - 80 + 15x - 15x$

$-5x = - 80$

Divide both sides by -5

$\frac{-5x}{-5} = \frac{-80}{5}$

$x = 16$

Y-1=5/6(x-4) in standard form

scoray [572]

   y - 1 = ⁵/₆(x - 4)
   y - 1 = ⁵/₆(x) - ⁵/₆(4)
   y - 1 = ⁵/₆x - 3¹/₃
   + 1    + 1
             y = ⁵/₆x - 2¹/₃
      ⁻⁵/₆x + y = ⁵/₆x - ⁵/₆x - 2¹/₃
   -6(⁻⁵/₆x + y) = -6(-2¹/₃)
-6(⁻⁵/₆x) - 6(y) = 14
         5x - 6y = 14
