Can anyone solve 84=4(1 - 4g) step by step?

lyudmila [28]

Answer:

g= -5

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

84-(4*(1-4*g))=0

84 - 4 • (1 - 4g) = 0

3.1 Pull out like factors :

16g + 80 = 16 • (g + 5)

16 • (g + 5) = 0

4.1 Solve : 16 = 0

This equation has no solution.

A a non-zero constant never equals zero.

4.2 Solve : g+5 = 0

Subtract 5 from both sides of the equation :

g = -5

Simplify and Evaluate

zalisa [80]

$\dfrac{2^{-1} + 5^{-1}}{10^{-1} - 5^{-2}} =$

$= \dfrac{\frac{1}{2} + \frac{1}{5}}{\frac{1}{10} - \frac{1}{5^2}}$

$=\dfrac{\frac{1}{2} + \frac{1}{5}}{\frac{1}{10} - \frac{1}{25}}$

$=\dfrac{\frac{5}{10} + \frac{2}{10}}{\frac{5}{50} - \frac{2}{50}}$

$=\dfrac{\frac{7}{10}}{\frac{3}{50}}$

$= \frac{7}{10} \times \frac{50}{3}$

$= \frac{7}{1} \times \frac{5}{3}$

$= \frac{35}{3}$
