H^-16/h^x=1/h^24 can someone help me please
Basile [38]

Given:

Consider the equation is

\dfrac{h^{16}}{h^x}=\dfrac{1}{h^{24}}

To find:

The value of x.

Solution:

We have,

\dfrac{h^{-16}}{h^x}=\dfrac{1}{h^{24}}

Using properties of exponents, we get

h^{-16-x}=h^{-24}       [\because \dfrac{a^m}{a^n}=a^{m-n},a^{-n}=\dfrac{1}{a^n}]

On comparing both sides, we get

-16-x=-24

Add 16 on both sides.

-x=-24+16

-x=-8

Multiply both sides by -1.

x=8

Therefore, the value of x is 8.

Please help IM SO CONFUSED!
rodikova [14]

Answer:

18

Step-by-step explanation:

You can see from the table that 2 bracelets are made every 30 minutes.

There are 9 intervals of 30 minutes each in 4.5 hours.

So, the number of bracelets that are made in 4.5 hours is

9x2=18

Another way to see this is to note from the table that 4 bracelets are made in 60 minute, which is 1 hour.  So, in 4 hours, 16 bracelets will be made. Also, from the table, 2 bracelets are made in 30 minutes, which is 1/2 hour.  So, adding up, 18 bracelets are made in 4.5 hours.
