Oops. Apologies. My mom is already telling me to go to sleep.

So the homework is very urgent?

Abundance is the amount that exists.

It should be relative abundance though......

If the relative atomic mass of chlorine is 35.5

That means the mass of the most abundant isotope must be less than 35.5 :)

Hope this helps :)

It is 21:49 GMT + 8 and I have to sleep at 22:15 GMT + 8. So half hour left.

If the equation is an equation with infinitely many solutions, then any numbers or values of the variable will satisfy the equation!!

e.g.: Variable(I don't know what it is, maybe t?) = $\dfrac{2\ln(3\pi)}{e^{\cos (\sin 20)}}$

Or simpler: Variable = 5 can satisfy the equation too!!

You'd better be quick..... I have to go to sleep soon......

Yeah.

Take a photo and post it on the forum :)

I can translate and help you do it :):)

Yes.

After turning 3x - 2y = 6 into y = 3/2 x - 3, it is easier to graph.

Because every point on a graph of a continuous function(just say function for your level...... continuous function is calculus thing) have a x-coordinate and a corresponding y-coordinate and the relationship between 2 of them is the function. Therefore we can calculate y coordinate and x coordinate just using y = 3/2 x - 3.

Cool :)

Btw where you from?

Me from Hong Kong :)
