Answer:
x*(2/3)=y
y*1.5=x
Step-by-step explanation:
There is 2/3rds the amount of sodium in the new one, y. If you multiply the odl one, x, by 2/3, you'll have the amount in the new one. Because half of 2/3rds is 1/3, if you multiply the new one by 1.5, you'll end up with 3/3, or 1, which is the amount in the old one.
We are given with a limit and we need to find it's value so let's start !!!!
But , before starting , let's recall an identity which is the <em>main key</em> to answer this question
Consider The limit ;
Now as directly putting the limit will lead to <em>indeterminate form 0/0.</em> So , <em>Rationalizing</em> the <em>numerator</em> i.e multiplying both numerator and denominator by the <em>conjugate of numerator </em>

Using the above algebraic identity ;


Now , here we <em>need</em> to <em>eliminate (√x-2)</em> from the denominator somehow , or the limit will again be <em>indeterminate </em>,so if you think <em>carefully</em> as <em>I thought</em> after <em>seeing the question</em> i.e what if we <em>add 4 and subtract 4</em> in <em>numerator</em> ? So let's try !


Now , using the same above identity ;


Now , take minus sign common in <em>numerator</em> from 2nd term , so that we can <em>take (√x-2) common</em> from both terms

Now , take<em> (√x-2) common</em> in numerator ;

Cancelling the <em>radical</em> that makes our <em>limit again and again</em> <em>indeterminate</em> ;

Now , <em>putting the limit ;</em>

Answer:
Least to greatest: 2, 3, 1
Step-by-step explanation:
Square root of 8 over 2 is about 1.41 which makes it the least value
2 is obviously equal to 2 which puts it in the middle
Square root of 7 is about 2.64 which makes it the greatest value
It would be: -2/3 * -9/10 = 18/30 = 3/5
So, option B is your answer.
Hope this helps!
6.5 is suppose to be on the inside of the radical sign.
