For each store, what is the ratio of the number of cans to the price.
stiks02 [169]
<span>Find the ratio of the number of cans in a store:
=> Shop smart = 24 packs (2 for $9)
=> super saver = 12 packs (4 for $10)
=> Price Buster = 12 packs (3 for $ 9)

Let’s start with the first, the shop smart
=> 2/24 = 9/x
=> 4.5 x 2 = 9, thus 4.5 x 24
= 108
=> 2:24 = 9/108

Second, Super Saver
=> 4/12 = 10/x
=> 4 x 2.5 = 10, thus 2.5 x 12
=> 30
=> 4:12 = 10:30

Third, Price Buster
=> 3/12 = 9/x
=> 3 x 3 = 9, thus 3 x 12
=> 36
=> 3:12 = 9:36

13x^-5 y^0/5^-3 z^-10
VMariaS [17]

Answer:

\frac{1625z^{10}}{x^{5}}

Step-by-step explanation:

We want to simplify:

\frac{13x^{-5}y^0}{5^{-3}z^{-10}}

We rewrite as positive index to get:

\frac{13y^05^{3}z^{10}}{x^{5}}

This simplifies to

\frac{13*1*125z^{10}}{x^{5}}

This will finally give us:

\frac{1625z^{10}}{x^{5}}

We cannot simplify further.

Hence the simplest form is \frac{1625z^{10}}{x^{5}}
