1. You set up a proportion to solve. If you divide 1 tablespoon of cocoa by 0.25 of water, the answer should be the same if you divide x cocoa by 1.5 cups of water.

So you set up the equation.

\(\frac{1}{\frac{1}{4}}=\frac{x}{\frac{3}{2}}\)

2. Then you solve by cross multiplying,

Try it yourself!

Thanks CPhill!

Thanks CPhill! I understand now!

1. We can plug in \((1,2)\) for both equations

\(x=\frac{1}{4}y+a\rightarrow 1=\frac{2}{4}+a\rightarrow\boxed{a=\frac{1}{2}}\)

\(y=\frac{1}{4}x+b\rightarrow2=\frac{1}{4}+b\rightarrow\boxed{b=\frac{7}{4}}\)

2. Then add:

\(\frac{1}{2}+\frac{7}{4}=\boxed{\frac{9}{4}}\)

That is the answer

If you have a score above 120, then you might have a chance

\(\boxed{\sqrt{7n}}\)

This is because \(a^\frac{1}{b}=\sqrt[b]{a}\)

So \(7n^\frac{1}{2}=\sqrt[2]{7n}=\sqrt{7n}\)

All I do is right click on the image I have and I click copy image address. Then when inserting the image, I just copy the address down.

For some reason, uploading the images on a Chromebook doesn't work. I think the Web2.0 Admin should fix that.

If the image can't be right clicked, the Chromebook actually has an automatic feature that captures any part of the screen just like Gyazo, so that's how I insert pictures.

I'm not sure if you are going to like how I solved the problem, but I solved it anyways.

We already know that \(40^2\) is 1600 and that \(50^2\) is 2500, that means the answer is between 40 and 50. Seeing that 2000 (2007 rounds to 2000) is closer to 1600, we try if \(44^2\) will fit the answer. \(44^2\) apparently is 1936, so the next possible solution is 45. Seeing that \(45^2\)is 2025, we can know that \(\boxed{18} \) years after 2007 will be the answer

If somebody finds a better way to solve this, please post it.

Electric Pavlov's answer except in clearer format

\((xy)*(\frac{1}{x}*\frac{1}{y})=\frac{xy}{xy}=\boxed{1}\)

You can plug your answer into both equations and check if they are true.
