Given the formula b=rs/t solve for s

Gekata [30.6K]

Answer:

$s = \frac{bt}{r}$

Step-by-step explanation:

To solve for s, you need to follow these steps.

First multiply by t both sides of the equation.

$b = \frac{rs}{t}$

$bt = \frac{rst}{t}$

We get $bt = rs$

Now we divide by r, both sides of the equation.

$\frac{bt}{r} = \frac{rs}{r}$

Finallly we obtain:

$\frac{bt}{r} = s$ or

$s = \frac{bt}{r}$

A bag holds 12 red marbles, 11 green

Blizzard [7]

Answer:

62.22%

Step-by-step explanation:

First, find how many total marbles there are:

12 + 11 + 17 + 5

= 45

Then, find how many marbles that are not blue:

12 + 11 + 5

= 28

Then, divide 28 by 45, and multiply by 100

(28/45) x 100

= 62.22% is the probability of not choosing a blue marble
