Vocaloid:

so on the left hand side you have -vp + 30 and you want v by itself how do we "get rid of" that + 30?

1 week ago

umm....-30 on both sides?

1 week ago
Vocaloid:

great, let's do that

1 week ago
Vocaloid:

-vp + 30 < 45 -vp < 15

1 week ago
Vocaloid:

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

1 week ago

um divide?...

1 week ago
Vocaloid:

good

1 week ago
Vocaloid:

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

Vocaloid:

now for 3w – 6r = 30 for r how can we "get rid of" that 3w on the left?

1 week ago

ummm -6r on both sides?

1 week ago
Vocaloid:

leave the -6r alone for now how can we "remove" the 3w?

1 week ago

3w subtract from both sides?

1 week ago
Vocaloid:

good, that gives us: – 6r = 30 - 3w how can we "get rid of" the -6 multiplied to r on the left hand side?

1 week ago

divide

1 week ago
Vocaloid:

ok, divide by what number?

1 week ago

-6r

1 week ago
Vocaloid:

just -6 since we want to leave r alone

1 week ago

oh right..

1 week ago
Vocaloid:

so we have: – 6r = 30 - 3w r = -(30-3w)/6

1 week ago

-5?

1 week ago
Vocaloid:

or more neatly:

1 week ago
Vocaloid:

r = (3w-30)/6

1 week ago
Vocaloid:

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

1 week ago
Vocaloid:

so that's it
