I need it by morning and I need the work HELP!!!

valentina_108 [34]

1. 5/6 = 10/12

3/4 = 6/8

2. 2/9 = 4/18

4/12 = 1/3

3. 6/7 = 12/14

1/2 = 2/4

4. 5/9 = 10/18

3/18 = 1/6

5. 1/6 = 2/12

1/9 = 2/18

6. 3/8 = 6/12

5/6 = 10/12

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.

Jill estimated she would spend $50.00 a month on clothing. However, at the end of the year she discovered she actually spent $71

RideAnS [48]

50$ per month for 12 years would mean she spent only (50 x 12) 600$ per year.

She actually spent $711, her forecast was off target by (600-7111) $111.

She exceeded her budget by $111
