That is not enough information   

Just do it on the calc on the home page.

To clarify: when you convert 2/3 to a denominator of 6, you do not multiply by 2, but rather 2/2. When you multiply fractions, you multiply the denominater by the denominator and the numerator by the numerator.

If you were to multiply 2/3 by 2, you would come out with a product of 4/3 or 1 1/3, because 2 is 2/1.

Another note: when you multiply on computers, you probably want to use asterisks (*) for multiplication.

Message me and I'll see if it works, your best bet is to post a question thou, then you can see many methouds of doing it

When you are trying to find the inverse sin of something it is usually press the 2nd button on your calculator and then the number you want to find it of. Or in most cases you put the value you want the inverse sin of and then you press the second and go over the sin button on your calculator.

hope I helped.

Message me and i can maybe help you, im taking Algebra 1 right now also

the second answer (2,8) is the correct one.   Thanks anon 2

Thank you also anon1 for you effort.  I like everyone to have a go.  It would have been good if you had checked by plugging your numbers  back into the original equation to see if they were both true.

Look for your error if you want help finding it let us know.    :)

If you ask a specific question, it would be easier to help you

To add these together you must get the same denominator which in this case you want 6. So you multiply the bottom by 2. And whatever you do to the bottom of the fraction you have to do the top which means you have to multiply the 2 by 2 aswell. and when you add them together it should look like this.

to clarify the reason i multiplied by to was to get the denominator to be the same. which is needed to be able to add them together. and i meant to say 2/2 but i just wrote 2. (woops)

2/3X2=4/6 +1/6 = 5/6

hope I helped.

Sure, why not. I can help you.

Great answer anon. thanks 

Firstly, what you want to do is to turn both of the equations into the same form. In this case, we'll be using standard form. We end up with -6x+y=-4. We can then begin to use elimination to solve the problem. Now, I'm hoping you actually learned how to do elimination so that this next part will make sense.

In order to solve the problem, we need to isolate one of the variables, x or y. In order to do so, we need to make the x's or y's from both equations opposites. In this situation, we'll rid of the x's. Because one of the equations has a negative and the other has a positive, that part of making the numbers opposite is complete. However, we still need to make them the same number to make them truly opposite. So, we need to multiply the equations to make the x's equal. Luckily, for this problem, we only need to multiply one of the two equations.

We firstly multiply this one by three to make the 2 equal 6.

3(2x+5y=44)=6x+15y=132

Now that the 6's are opposites, we can now proceed with the rest of the problem

  6x+15y=132    Now we will we will add the terms together.

 -6x+y=-4            6x+(-6x)=0   15y+y=16y   132-4=128

Now put those back into the equation. Because there is no more x, we are left with:

16y=128    Simply divide 128 by 16 and you get 8. Hence, y=8. However, this is only the first part of the problem. We now use the y to find the x by putting the value of y back into the equation made previously. To keep it simple, let's use -6x+y=-4. Put the value of y, 8, back into the equation and solve.  

-6x+8=-4  x=2 

So, now that we know x, the point at which the two lines cross is at: (2, 8)

I hope I did this right and that it helps. Good luck!!! 

Hello. 3.6 multiplied by 10 to the fifteenth means how many times you will move the zero the right. So the answer would be.... 3600000000000000. However this trick only works when the number that has a power is a ten.

3.6 x 10^15 = 3600000000000000

jm,

2x+5y=44       y=6x-4 First you need to get x and y on the same side in both equations.

y=6x-4    =>   0=6x-4-y   =>    4=6x-y     Then you multiply the first equation by 3.

2x+5y=44    =>    6x+15y=264    Next subtract the second equation from the first.

     6x+15y=264

 -   6x-y=4

     16y=260    Divide each side by 16   =>   y=16.25

Plug y back into the equation and solve for x   =>    2x+5(16.25)=44   =>   2x+81.25=44   =>   2x=-37.25

x=-18.625    y=16.25

Here is how you would solve your question. I'll do the first 3

$${\frac{{\mathtt{450}}}{{\mathtt{15}}}} = {\frac{{\mathtt{n}}}{{\mathtt{1}}}}$$    To solve for n, you start with your 450 and multiply it to the number diagonal to it. Here, we find that it is 1. After we multiply, we would then divide the number underneath the 450 you started with. Hence, we divide 450 by 15 and, in this case, n would equal 30, therefore meaning Moe can drive his car thirty miles with one gallon of gas. 

$${\frac{{\mathtt{450}}}{{\mathtt{15}}}} = {\frac{{\mathtt{n}}}{{\mathtt{2}}}}$$   (450*2=900  900/15=60)This time, he could travel sixty miles with two gallons of petro.

$${\frac{{\mathtt{450}}}{{\mathtt{15}}}} = {\frac{{\mathtt{n}}}{{\mathtt{3}}}}$$   (450*3=1,350  1,350/15=90) With this one, we can see that Moe could travel ninety miles with three gallons of gasoline.

Hope this helps. Good luck!

1/2=.5   =>   .5x2=1

Another way to think about it is that 1/2 is half of 1. You need 2 halfs to make 1.

Woof

$${\mathtt{x}} = {\mathtt{6}}$$

$${\mathtt{9}}{\mathtt{\,\small\textbf+\,}}{\mathtt{10}} = {\mathtt{19}}$$

Idk man. It must suck. Btw you sound like an incredibly sexy person!

Wow ! He was more than 700 years old. Was that why he was so good at mathematics ?

Use this formula:

V = pi * r² * h 

Where pi ≈ 3.14, r is the radius and h is the height.
