Answer:

[tex]t = \frac{-D+F}{Dr}[/tex]

Step-by-step explanation:

Step 1: Flip the equation.

  • [tex]Drt + D = F[/tex]

Step 2: Subtract D from both sides.

  • [tex]Drt + D - D = F - D[/tex]
  • [tex]Drt = -D + F[/tex]

Step 3: Divide both sides by Dr.

  • [tex]\frac{Drt}{Dr} = \frac{-D+F}{Dr}[/tex]
  • [tex]t = \frac{-D+F}{Dr}[/tex]

good job
