O.O i alredy got a problem! a/5 + 8 = 9! its not tht hard, but its hard fer me since i take 9th grade math, im skipping 8th grade algebra!! Cathcing up is hard, try to help, k?

Answer 1

a/5 + 8 = 9

a/5 = 9 - 8

a/5 = 1

a/5 * 5 = 1 * 5 (we do this so we get a by it self to work out what a is)

a = 5

Answer 8

Answer 10

=)

Answer 11

\[\frac{a}5 + 8 = 9!\]
\[a= 1814360\]
;)

Answer 12

tht can not be correct!

Answer 13

write out your next question seperately not on this same page

Answer 14

ok

Answer 15

a/5 + 8 = 9!
a/5 = 9! - 8
a = 5( 9! - 8)
a= 5( (9*8*7*6*5*4*3*2*1) -8 )
a = 5( 362880 - 8 )
a = 5 ( 362872)
a = 1814360

Answer 16

if u say this, then u r saying 1814360 / 5 + 8 = 9, tht is not true

Answer 17

the answer is a=5

Answer 18

I'm saying
1814360/5 +8 = 9!
which is true.

Answer 19

which is what you wrote.

Answer 20

look on the calculator, its not =)

Answer 21

did you not understand the way i wrote it out? if you did then i would stick with that method otherwise it may just confuse you more looking at other methods

Answer 22

my calculator says I'm right.

Answer 23

no lilg132, i completely understand lol. when i come up with other questions i will post them. Your answer makes complete sense to me.

Answer 24

lilg132 has a correct solution to a question that is similar--but different from what you asked. I have given you the solution to the question you asked.

Answer 25

??? im so confused!!! both questions r the same!! and i dont kno y tht calculator says agreene's answer is correct. If u use the calculator in the start menu located on the desktop, it says lilg132's answer

Answer 26

can u plz tell me what is the difference between lilg132's question and yours?

Answer 27

probably because lig132 is answering:

a/5 +8 = 9
and I am answering
a/5 +8 = 9!
and
9 isnt the same as 9!

Answer 28

what's 9! ? lol tht was an exclamation mark!! i didnt even know an exclamation mark was a math symbol. lol!

Answer 29

9! is
9*8*7*6*5*4*3*2*1 its 362880
or if you prefer this notation:
\[9\times8\times7\times6\times5\times4\times3\times2\times1=362880\]

n! = n*(n-1)*(n-2)*...*3*2*1
