Good, Well done..

Answer 5

yep good yah !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! :)

Answer 6

what about this one?

Answer 7

what you get when you solve first one which is 5a + 12 < 2

Answer 8

Calculate the same for first one..

For second you have got \(a < 3\), which is right..

Answer 9

@Nnesha the first one was a < -2 but that is clearly irrelevant because the second one was a < 3

Answer 10

only a few more(: thank you everybody

Answer 11

Yes, you are right, x = 5..

Answer 12

can someone walk me through this one please?

Answer 13

I think in that you have to write both, a < -2 as well as a < 3 too..
Are you given with any answer choices?

Answer 14

What do you think?

Answer 15

no, that one is something i have to write. i did write an explanation about the -2 tho beneath it

Answer 16

No..

Answer 17

@Nnesha i dont think so... the -2 is just irrelevant

Answer 18

a is in between -2 and 3 if a > -2 and a < 3 which is not the case here..

Answer 19

@Nnesha it is simple to check:

For first one a < -2, let us take a = -1, it will not satisfy first inequality, as -1 is greater than -2 and not less than..

Answer 20

can someone please walk me through the one i asked?

Answer 21

yeah i understand thanks

Answer 22

ok so last one when you take a absolute value of a number you left with two answer positive and negative

Answer 23

See, for mods, one time you take positive and next time you take negative of it..

|3x|>= 21

It implies that:
3x >= 21 or -3x >= 21

Just solve the two inequalities..

Answer 24

ahhhh. gracias

Answer 25

now just solve for x
be careful with second one
