Your variable would be t. Anytime you see a letter in an equation, that will be your variable :)

This is like the equivalent to a jar with 4 green balls and 6 white balls, where you are picking 3. (The 4 green balls signify the friends from kindergarten.)

You want to solve the probability that the first two balls are green and the third is white.
First draw --> 4 green out of 10 balls --> 4/10 = 2/5

Second draw --> 3 green out of 9 balls --> 3/9 = 1/3

Third draw --> 6 white out of 8 balls --> 6/8 = 3/4

2/5 x 1/3 x 3/4

= 6/60

= 1/10

so the answer is 1/10 (or 10%)

Answer:

It will take Josie 80 minutes to run 10 miles.

Step-by-step explanation:

We can set up a proportion between the number of minutes she runs to the number of miles she runs. From what we know in the equation, we know that it takes her 24 minutes to run 3 miles, and it takes x minutes to run 10 miles. We can represent this in a proportion!

We know that the ratio of 24:3 will be the same for any number of miles, so we can say

$\frac{24}{3} =\frac{x}{10\\}$
