Solve this algebraically for the exact values (Meaning find the x-intercepts): (1/x)=x/(3x+18) I'm not sure what to write as the common denominator. I thought it was: 4x+18 because (3x+x+18)=(4x+18), but I'm not sure what to do from there. Thanks!

use the variables p for plane and w for wind and the equations: (p+w)x 2hours = 360 miles (p-w)x 2hours = 300 miles divide by 2 p+w=180 p-w=150 combine the two equations so w cancels out 2p = 330 divide by 2 to get the speed of the plane. p=165 put the pl...

Pi never ends and it never repeats a sequence.

You asked this twice ;) Not even going to guess? Let me give you some hints: What variables are the same for each? B) does not address the variable They know what condensation is.

Thanks! Great answer. :)

Yes sir! Nice work.

Is there a question in there?

No, it's C D gives you the number for length and width multiplied together. Sorry Luis

you want H (aka height) Volume = length x width x height Volume/(Length x width) = height

Step by step: You want the variable "x" on one side. first: Remove -9 from the right y adding 9 to each side to get: 5x + 11 = 4x Get the other term with "x" in it by subtracting 5. From both sides. Remember that 5x and 4 x are the same term because the b...

PS: You don't need to start with the -9. You can start from either side. For example: you could have subtracted 2 from both sides to get -11. 5x-11=4x Then keep going

Don't worry. Just remember you need to find x. You can't do that with x on both sides, right? It's in 5x and 4x. Get x to one side. Remove 5x from the right. Whatever you do to one side you do to the other. 4x-5x=-1x (do not remove x as it can be any numb...

Hint: How many red socks are left after she removes one? How many socks are there in total?

Never mind I figured it out!

Oops, the units for gravity are incorrect, it should me m/s^2.

Not a question.

Thanks for typing that all out! It really helped.

I think you're right for all.

So, g-g=0 wouldn't that get me g(x)=0?

nm. I figured it out :)
