Explain how you can find 3*584 using expanded form
Julli [10]

The expanded form of 584 is:

584 = 500 + 80 + 4

Therefore:

3 · 584 = 3 · ( 500 + 80 + 4 )

Then we will use Distributive property : we can multiply a sum by muptiplying each addend separately and then add the products.

3 · 500 + 3 · 80 + 3 · 4 = 1,500 + 240 + 12 = 1,752

Finally: 3 · 584 = 1,752.

Your sock drawer in all mixed up! You
Makovka662 [10]

Step-by-step explanation:

There are 21 socks in total. Only 7 of them are white.

When you pick your 1st sock, you have a 7/21 chance to get white.

When you pick your 2nd sock, you have a 6/21 chance to get another white, since you already picked a white.

So the probability to get a pair of white socks is 2/21.
