Answer:

Step-by-step explanation:

4x-40=7(-2x+2) multiply inside the parenthesis with 7

4x - 40 = -14x + 14 export like terms to the same side of equation

4x + 14x = 14 + 40 add like terms

18x = 54 divide both side by 18

x = 3

<h3>Answer:  8</h3>

=====================================

Work Shown:

y = 192\left(4^{x-3}\right)\\\\196,608 = 192\left(4^{x-3}\right)\\\\\frac{196,608}{192} = 4^{x-3}\\\\1024 = 4^{x-3}\\\\4^{x-3} = 1024\\\\\log\left(4^{x-3}\right)=\log\left(1024\right)\\\\(x-3)*\log\left(4\right)=\log\left(1024\right)\\\\x-3=\frac{\log\left(1024\right)}{\log\left(4\right)}\\\\x-3=5\\\\x=5+3\\\\x=8\\\\

It will take 8 hours for the population to reach 196,608 bacteria.

Hey there!!

We know angle DEC = angle AEB

Hence,

... 4x + 12 = 5x - 10

... - x = - 22

... x = 22

4 ( 22 ) + 12

88 + 12

100° is the answer.

Hope my answer helps!
