Let me slightly correct blondie here.

Mode is the number that appears most frequently in a data set......[if no number appears more than once, the data set is said to be unimodal ]

Median is the middle number in a data set arranged from least to greatest.....if there are an even number of values.....we sum the middle two values and divide this sum by 2 to get the median

[That's OK, blondie.....I srill gave you some points !!!  ]

Totally 45!!!!

answer

lol 21

jk its 19

Lin sold 4 more shirts than Greg. Fran sold 3 times as many shirts as Lin. In total, the three sold 51 shirts. Which represents the number of shirts Greg sold?

Let x be the total number that Greg sold

And x + 4 the number that Lin sold

And 3(x + 4) the number that Fran sold

So we have

x + x + 4  + 3(x + 4) = 51   simplify

5x + 16  = 51      subtract 16 from both sides

5x = 35     divide both sides by 5

x = 7 = the number Greg sold

i thinks its 8181.231

-20-18+(-29)=-38-29=-67

is what real?

You can type it in as   82*(tan(34.2) - tan(31))  on the onsite calculator

it is like a fraction right?

43/12

or 

3 7/12

24 = (8/10) C     where c is the class size.....multiply both sides by 10/8

24(10/8)  = C =  30 students in the class

Those letters are real!! "monkeynippels"

Yep, blondie.....that what it looks like.....can you get the answer ???

A prime number is one that has no other factors except itself and 1   [Ex:  17 = 17 x 1]

A composite number is one that has factors other than itself and 1  [ Ex : 12 =  2 x 2 x 3 ]

BTW  - The Fundamental Theorem of Arithmetic  says that every integer greater than 1 can be expressed as a product of primes  or is itself prime

Yes it is so real!!!!!

is what real

are you finding the volume of a sphere?

I'm assuming the x's are multiplication signs so 

7(7) [ 67(7) +  28(7)(7) ] * 7 = 

7(7) [469 + 1372] * 7 

7(7) 1841 * 7

49 * 1841 * 7

90209 * 7

= 631463

You just have to plug in the V's for 7's.

* = multiplication sign.

If the brackets confuse you, they just are paratheses.

what does / mean 

in your equasion if you happen to answer then i may have the answer

Notice that  -(-4.9)  = +4.9

So adding this to another positive results in a positive......
