Answer 2

@Vocaloid please help

Answer 3

so on the left hand side you have -vp + 30 and you want v by itself

how do we "get rid of" that + 30?

Answer 4

umm....-30 on both sides?

Answer 5

great, let's do that

Answer 6

-vp + 30 < 45

-vp < 15

Answer 7

how can we "get rid" of that "p"?

Answer 8

um divide?...

Answer 9

good

Answer 10

so now we have

-v < 15/p

now we just multiply both sides by -1 (making sure we flip the inequality around) giving is

v > -15/p as our answer

Answer 11

now for 3w – 6r = 30 for r

how can we "get rid of" that 3w on the left?

Answer 12

ummm -6r on both sides?

Answer 13

leave the -6r alone for now

how can we "remove" the 3w?

Answer 14

3w subtract from both sides?

Answer 15

good, that gives us:

– 6r = 30 - 3w

how can we "get rid of" the -6 multiplied to r on the left hand side?

Answer 16

divide

Answer 17

ok, divide by what number?

Answer 18

-6r

Answer 19

just -6 since we want to leave r alone

Answer 20

oh right..

Answer 21

so we have:

– 6r = 30 - 3w

r = -(30-3w)/6

Answer 22

-5?

Answer 23

or more neatly:

Answer 24

r = (3w-30)/6

Answer 25

we can't simplify this further because we don't know what w is

Answer 26

so that's it

Answer 27

yay awesome thanks
