Answer 4

I can help you with the first one - but please post the others (one at a time) as separate questions after this. You should be able to edit your question and remove al but the first question from here.

Answer 5

so the first question is to simplify this - correct?\[\frac{4x}{9}-\frac{x-10}{9}\]

Answer 6

correct

Answer 7

ok, first thing to notice is that both fractions have the same denominator (9).
this means that you can combine the numerators above it as follows:\[\frac{4x}{9}-\frac{x-10}{9}=\frac{4x-(x-10)}{9}\]understand?

Answer 8

makes sence

Answer 9

ok, now see if you can simplify the numerator by removing the braces

Answer 10

4x^2-10/9?

Answer 11

you have multiplied here which is not correct.
the first step is to just remove the braces from:\[4x-(x-10)\]this then becomes:\[4x-(x-10)=4x-x+10\]

Answer 12

ooooh okay that makes more sence lol

Answer 13

the -10 inside the braces becomes +10 because of the rule (minus and minus makes a plus)

Answer 14

okay then what?

Answer 15

now combine "like" terms in:\[4x-x+10\]what do you get?

Answer 16

3x+10?

Answer 17

perfect!

Answer 18

so is that my answer??

Answer 19

so we end up with:\[\frac{4x}{9}-\frac{x-10}{9}=\frac{4x-(x-10)}{9}=\frac{4x-x+10}{9}=\frac{3x+10}{9}\]

Answer 20

ah okay.... i was wondering what we did with the 9 haha well thanks!! :)
