Given that Sara put 7 boxes in her closet.

So number of boxes = 7

Then it says that each box is for holding a different type of seashell. So far, there are 0 shells in each box.

So the number of seashell in 1 box = 0


We need to find about how many shells does Sara have.

To find that we will just multiply (number of boxes) by (number of seashell in 1 box). Which is given by 7 times 0.


we know that product of a number and 0 is always 0.

Hence final answer is 0 seashell.

BlackZzzverrR [31]

Answer:

w = 40 miles per hour

r = 300 miles per hour

Step-by-step explanation:

We add w with the wind and subtract w against the wind

r+w = 340 miles per hour

r - w = 260 miles per hour

Add the two equations together to eliminate w

r+w = 340 miles per hour

r - w = 260 miles per hour

----------------------------------------

2r = 600

Divide by 2

r = 300 miles per hour without the wind

Now find w

r+w = 340

300 + w = 340

Subtract 300

w = 340-300

w = 40 miles per hour
