Question

HELP PLEASE ANYONE!

Answer 1

if c<0 then c must be a negative number
if d<0 then d must be a negative number

negative / negative = positive

ie if c = -6
and d = -2

then c/d = -6/-2 = 3

Answer 2

does that help...?

Answer 3

What?! @Jack1

Answer 4

i dont really understand your steps method there, sorry, i understand the maths and it makes perfect sense to me that -ve / -ve = +ve,

but as for labelling each of the steps on how you get there according to it's mathematical description... i'm out, sorry, it's just... one step, it that makes sense

Answer 5

I have to label the steps... but anyway thanks!

Answer 6

@Jack1 Can you help me label them?

Answer 7

For step three for example, would B be correct?

Answer 8

i think 20 is C... is tht what you were thinking?
and why do you think 19 is B?

Answer 9

and i do think... that by elimination you could come to the conclusion that 19 is B.... im not 100% sure because i learned these properties and proofs years and years back

Answer 10

@aykayyy Thanks for your help :) Yes I also thought that 20 is C, but for 19 I am not 100 % sure also :(

Answer 11

i'd go with B because im pretty sure the others are wrong haha

Answer 12

I was thinking that 19 might be D ?

Answer 13

umm actually you may be right! because the step is basically showing that the right side gets multiplied by 0 and becomes 0.

Answer 14

Thanks a lot! :) Hopefully I am right! :(:(
