a)

  F  = \frac{5}{9}(K - 273.15) + 32

<u>- 32</u>    <u>                      - 32</u>

F - 32 = \frac{5}{9}(K - 273.15)

\frac{9}{5}(F - 32) = \frac{9}{5}[\frac{5}{9}(K - 273.15)]

\frac{9}{5}(F - 32) = K - 273.15

\frac{9}{5}F - \frac{9(-32)}{5} = K - 273.15

\frac{9}{5}F - 57.6 = K - 273.15

<u>     + 273.15</u>    <u>   + 273.15  </u>

\frac{9}{5}F - 215.55 = K

b)

\frac{9}{5}(180) - 215.55 = K

324 - 215.55 = K

108.45 = K

Write the log equation as an exponential equation.<br>log3(4x) = 2​
gayaneshka [121]

Answer:

x  =9/4

Step-by-step explanation:

log3(4x) = 2​

Raise each side to the base of 3

3^ log3(4x) = 3^2

We know that 3log3 is 1

4x = 9

Divide each side by 4

4x/4 = 9/4

x = 9/4​
