### Commemorative coins come in packs of 15,while coin holders come in packs of 25. What are the least numbers of packs you should buy in order to have the same numbers 9f coins and coins holders

**Answer:**

5 packs of commemorative coins and 3 packs of coin holders.

**Step-by-step explanation:**

We have been given that commemorative coins come in packs of 15,while coin holders come in packs of 25.

To find the least number of packs, we need to find LCM of 15 and 25.

Multiples of 15: 15, 30, 45, 60 ,75, 90,..

Multiples of 25: 25, 50, 75, 100,...

We can see that least common multiple of 15 and 25 is 75.

**Therefore, you should buy 5 packs of commemorative coins and 3 packs of coin holders.**

'mu' is a letter in the Greek alphabet. It looks like this: μ

If you need labels for quantities or variables in math or science,

you can use any letter from any alphabet you like ... just be sure

to explain what the symbol stands for somewhere on the page

where the equation or formula is.

I've seen 'mu' used to stand for 'micro-' when writing units.

For example:

" μ-meter " ... one millionth of a meter

" μ-farad " ... one millionth of a farad

" μ-second " ... one millionth of a second

### My algebra math book has this math problem ---> 4a - 3b = 21. i am supposed to figure out if it is true or false. but the thing is, i do not know how to do this so that i can find out if it is true or not. PLEASE HELP!!!!!

The value of (4a - 3b) depends on what 'a' and 'b' are.

There are many combinations of 'a' and 'b' that make

(4a - 3b) equal to 21, and a whole bunch of others

that don't.

The equation in your question is not true OR false until you know

what 'a' and 'b' are. I suspect that right next to this problem in your

math book, it gives you some values for 'a' and 'b'.

Here are a few examples of how to do it:

1). I tell you that a=2 and b=1.

You take those numbers, and write them in place

of 'a' and 'b' in the left side of the equation:

4a - 3b

4(2) - 3(1)

8 - 3 =

**5**

If a=2 and b=1, then the left side of the equation is 5, not 21,

and the equation is false.

================================

2). I tell you that a=5 and b=4.

You take those numbers, and write them in place

of 'a' and 'b' in the left side of the equation:

4a - 3b

4(5) - 3(4)

20 - 12 = 8

If a=5 and b=4, then the left side of the equation is 8, not 21,

and the equation is false.

=================================

3). I tell you that a=6 and b=1.

You take those numbers, and write them in place

of 'a' and 'b' in the left side of the equation:

4a - 3b

4(6) - 3(1)

24 - 3 = 21

If a=6 and b=1, then the left side of the equation is 21,

and the equation is TRUE.

This is not the only possible pair of numbers for 'a' and 'b'

that make the equation true. There are tons of possibilities.

Look around the question in your book and see if it gives you

values for 'a' and 'b' to test in the equation.

Average velocity =

(distance between start-point and end-point) / (time from start to end)

in the direction of

(direction from the start-point to the end-point) .

a). The average velocity for the first half is

(50m)/(20sec) =

**2.5 m/s south.**

b). The average velocity for the second half is

(50m)/(22sec) =

**2.273 m/s north**

c). Average velocity for the round trip is

**zero**, because

the start-point and end-point are the same point.

However ...

Average SPEED = (total distance covered) / (time to cover the distance)

Average SPEED for the round trip is
