Answer 10

What do they call .25 cent in Australia?

Answer 11

the closest we have is a 20 cent piece

goes

5c coin
10c coin
20c coin
50c coin
1dollar coin
2dollar coin
5dollar note
10dollar note
20dollar note
50 dollar note
100 dollar note
not sure about any higher values if we have them, they aren't in common use

and we dont have any special names for any of them except nicknames (like 10 dollar note is a bluey, or 20 is a lobster, 50 is a pineapple all because of the colour)

Answer 12

you're actually funny lol

Answer 13

thanks

Answer 14

would you be willing to do another problem?

Answer 15

i can try

Answer 16

solve for "x" : fh/2x= mn

Answer 17

does that mean you have 5 unknowns?

Answer 18

??

Answer 19

what is fh and mn?

Answer 20

just variables, we are only solving for "x".

Answer 21

you can still have variables in your answer.

Answer 22

yeah, but if you need to solve for x and you dont know if fh and mn are constants or variable, you need to change how you ansewr the question

Answer 23

ok
fh/2x=mn

fh/mn=2x

(fh/mn)/2=x

Answer 24

hmm let me see.. i think that's it

Answer 25
