Answer:

The answer is,

r =  \frac{3t}{t - 1}

Step-by-step explanation:

t =  \frac{r}{ r - 3}

Firstly, you have to get rid of fraction by multiplying (r-3) to both side and expand out:

t × (r-3) = r/(r-3) × (r-3)

rt - 3t = r

Then you have to move all the "r" variables to one side and other variables to the other side:

rt - r = 3t

You can make "r" as a subject by taking out the common term, you can see that the common term on the left is "r" so you can bring out:

r(t-1) = 3t

r = 3t/(t-1)

Write the equation for the following relation. Include all of your work in your final answer.
Tamiku [17]

Given:

The relation is

Q=\{(x,y):(2,8),(3,27),(4,27),(5,125),...\}

To find:

The equation for the given relation.

Solution:

(2,8) is an ordered pair of given relation. So, y=8 at x=2.

8=2\times 2\times 2

8=2^3

Similar,

27=3^3

64=4^3

125=5^3

It means, y-values are cube of x-values. So,

y=x^3

Therefore, the required equation for the relation is y=x^3.

The perimeter of the new m-phone is 16 inches. The phones length is 5.25 inches. What is the width of the phone
True [87]
Perimeter is all the sides added up together.
Divide 16 by 2, so that you can get just a measurement of the length and the width.

16/2 = 8

Since the length is 5.25, subtract that by 8.

8-5.25 = 2.75

The width of the phone is 2.75 inches.
