How do i solve this equation?

ax-c=bx d



how do i solve for x?
do this:

ax-bx=d c (get Xs on one side)

x(a-b)=d c (factor out x)

x = (d c) / (a-b) (divide by (a-b))
ax-c=bx d



solution



ax-bx=c d



x(a-b)=c d



x=(c d)/(a-b)

What evidence contradicted the idea that heat was a fluid?

from count rumford
The fundamental observation is that a hot object does not lose mass as it cools. If heat were a fluid, cooling would cause a loss of mass and heating would cause an increase of mass.
From what I remember from high-school, it was a realization that it contradicted the laws of conservation (you could

I need to make a air tank on the cheap ? pvc?

i need to make a 300 gallon tank for like 30$ :D



also are there really wide pvc pipes so that i could achieve this?

like 4 feet wide and 6 feet tall?
it depends on how much pressure you need in this tank.



if the pressure is low then maybe you could get a couple of plastic barrels and join them. For the price you mention, I doubt you will be able to get a pipe this size.
For $30?

Calculate the mass of 2.50 mol of CH3OH(1)?

Just multiply the number of moles by its molar weight



molar weight of CH3OH:

C = 1 x 12.0 = 12.0

O= 1 x 16.0 = 16.0

H= 4 x 1.01 = 4.04



Total = 32.04 g/mole



(2.50 moles)(32.04 g/mole) = 80.1 g

What is the difference between bacteria ad germs?

germs is the common term used to identify the microorganisms which cause diseases to humans

it is not a scientific term

bacteria are one of the groups of microorganisms (others are, viruses, fungi , algae)

they may be useful to us and cause harm to us at the same time

all germs are bad to the body but not all bacteria
Germs don

In the graph, vertex S of figure RSTW has the coordinates (15,9). If RSTW is reflected across the X-axis what?

Good Morning,



I am baffled by this question and hopes someone could explain to me how the book got the answer.

In abiogenesis, when did DNA evolve?

I think you need to distinguish between evolution and the origins of DNA. Evolution is usually a term that is reserved for changes in living organisms, and you are asking a question that goes back to the time before organisms.



In most conceptions of the origins of what are now considered biomolecules proteins and RNA precede DNA. There are different ideas of how the stuff of life started, though it

Momentum question please help!?

A 15 kg penguin waddling east at a velocity of 7 m/s collides with a stationary 10 kg penguin. After the collision the 15 kg penguin is traveling at a velocity of 4.2 m/s 20 degrees S of E.

a) what is the velocity of the 10 kg penguin after collision?

b) is this collision elastic or inelastic?



i have no idea how to do this question, step by step explanation please, much appreciated!
(a)Let the velocity of 10 kg penguin is v m/s after the collision,

How big will a circle be if 4320 ft of rope is used?

We can apply the formula for calculating the circumference of circles, which is diameter = circumference. In this case, we have the circumference (4320 feet). To calculate the diameter, we can re-arrange the equation a little, and the answer is (4320 Ft ), which is 1375.0988 feet (correct to 4 decimal places).

Questions about opening a zoo?

when im older like 25 what does it take to open a zoo i have a big interest in animals and if you own a zoo can you make contact with some of the animals? do feeders make contact with the animals?
It takes a lot of work to open a zoo. First you should get some degrees in zoology, marine biology if you plan to have marine animals, and business would be some good things to start with. You also need to buy a large plot of land. Then you
