Answer:
She has 15 more purple rocks than blue.
Step-by-step explanation:
purple= 2/3 of all rocks
blue= 3/4 of all rocks that aren't purple
silver= 3 (or 1/4 of all rocks that aren't purple)
if 3 (silver) is 1/4 of all rocks that aren't purple, blue (3/4) is 3x3=9
if purple is 2/3 of all rocks, blue and silver are 1/3 of all rocks
so 1/3 of all rocks would be 9+3=12
if 1/3=12, then 2/3 (purple)=24
-----
At this point:
purple=24
blue=9
silver=3
-----
purple (24) - blue (9) =15
She has 15 more purple rocks than she does blue.
Answer:

Step-by-step explanation:
Simplify the following:
⇒-9 x + 12 x + 10
Grouping like terms:
⇒(12 x - 9 x) + 10
12 x - 9 x = 3 x:
⇒3 x + 10
The limit is presented in the following undefined form:

In cases like this, we can use de l'Hospital rule, which states that this limit, if it exists, is the same as the limit of the derivatives of numerator and denominator.
So, we switch

The derivative of the numerator is

Whereas the derivative of the denominator is

So, the new limit is

So, it would seem that we didn't solve anything, but indeed we have! Recall the limit

to conclude that the limit converges to \dfrac{6}{25} [/tex]
