Answer 2

about time u got here

Answer 3

Lol, sorry I'm helping other people..

Answer 4

P = mgh

This is just like solving a regular equation but there are letters instead of numbers.

To get h by itself you have to get rid of the mg that's being MULTIPLIED by h, and to get rid of it you have to do the opposite, and what's the opposite of multiplication?

Answer 5

division

Answer 6

so we know its not a are d but its b and c I say b

Answer 7

Yes the opposite is division so we divide mg to both sides.

That's going to give us \(h = \dfrac{P}{mg}\)

So which choice is our answer?

Answer 14

Okay, that's fine.

Answer 15

Which literal equations are equivalent to m=w/g?

A. g=w/m

B. g=m/w

C. w=mg

D. w=m/g

Answer 16

It's asking which equations are same as that one.

Let's solve for g in m = w/g

m = w/g

Multiply g to both sides:

mg = w

Divide m to both sides:

g = w/m

So g = w/m is one of our choices.

Answer 17

Now let's solve for w in the equation m = w/g

m = w/g

Multiply g to both sides:

w = mg

So w = mg is our second choice.

Answer 18

There are only two correct choices..what are they? @rayman5766

Answer 19

a and c also are u human

Answer 20

Yep, you got them.

And yes I am..lol. Why do you ask?

Answer 21

Which literal equation is equivalent to y = 0.4x?

A. x=0.4y

help

Answer 24

@iGreen

Answer 25

@iGreen help me pls I know I am not the only one but i just realized its 11:47

Answer 26

y = 0.4x is the same thing as 0.4 = y/x

Answer 27

soits a

Answer 28

its A

Answer 29

It's D..because D has 0.4 = y/x in it..
