Solve for t in scientific formula d=rt
yarga [219]
The problem is: d=rt
you are solving for r

d=rt
--  --
t    t


you divide both sides by r, so your answer is:

d/t=r or r=d/t

I hope this helped! :))

leonid [27]

Answer:

The answer to your question is  7 and -1/7

Step-by-step explanation:

Data

First line                        Second line

B (4, 4)                            A (0, 1)

M (3.5, 0.5)                     C (7, 0)

Formula

Slope = m = (y2 - y1) / (x2 - x1)

Process

1.- Calculate the slope of the first-line

    x1 = 4        y1 = 4

    x2 = 3.5    y2 = 0.5

-Substitution

    m = (0.5 - 4) / (3.5 - 4)

-Simplification

     m = -3.5 / -0.5

-Result

     m = 7

2.- Calculate the slope of the second line

    x1 = 0          y1 = 1

    x2 = 7         y2 = 0

-Substitution

   m = (0 - 1) / (7 - 0)

-Simplification

   m = -1/7

-Result

   m = -1/7
