1-6\log { \left( 6x-7 \right)  } =13\\ \\ -6\log { \left( 6x-7 \right)  } =12

\\ \\ \frac { -6\log { \left( 6x-7 \right)  }  }{ -6 } =\frac { 12 }{ -6 } \\ \\ \log { \left( 6x-7 \right)  } =-2

\\ \\ { 10 }^{ -2 }=6x-7\\ \\ 6x-7=\frac { 1 }{ 100 } \\ \\ 6x=7+\frac { 1 }{ 100 }

\\ \\ 6x=\frac { 700 }{ 100 } +\frac { 1 }{ 100 } \\ \\ 6x=\frac { 701 }{ 100 }

\\ \\ \frac { 1 }{ 6 } \cdot 6x=\frac { 1 }{ 6 } \cdot \frac { 701 }{ 100 } \\ \\ x=\frac { 701 }{ 600 }

D:6x-7>0\\
D:6x>7\\
D:x>\dfrac{7}{6}\\\\
1-6\log(6x-7)=13 \\
6\log(6x-7)=-12\\
\log(6x-7)=-2\\
10^{-2}=6x-7\\
6x-7=\dfrac{1}{100}\\
600x-700=1\\
600x=701\\
x=\dfrac{701}{600}

Four percent of Jennie's skin cells were burned when she escaped from a fire. If 3.7 x 10^10 of her skin cells were burned then,
baherus [9]

Answer:

355.2

Step-by-step explanation:

Given:

Four percent of Jennie's skin cells were burned

Total skin cells having Jennie = 3.7 x 10^10

                                                  = 3.7\times10\times10 = 370

To find:

How man skin cells were not burned ?

Solution:

Total skin cells having Jennie = 370

Percent of Jennie's skin cells were burned = 4%

Skin cells burned  from a fire = 370 \ of 4\%

                                                = 370\times\frac{4}{100} =\frac{1480}{100}

                                                = 14.8

Remaining skin cells which not burned = 370 - 14.8 = 355.2

Therefore,  355.2 skin cells were not burned.
