2(4 + 2x) ≥ 5x + 5
Simplify.
8 + 4x ≥ 5x + 5
Subtract 8 from both sides, as well as subtracting 5 from both sides.
4x - 5x ≥ 5 - 8
Simplify.
-x ≥ -3
Divide both sides by -1.
x ≤ 3
~Hope I helped!~
2 = X = -1

2. 2(4x+2) - (x-4) = 3(x+2)
Expand tge expression
= 8x + 4 -x +4 = 3x + 6
CLT ( Combine like terms)
= 7x + 8 = 3x + 6
Rearrange the terms
7x - 3x = 6 - 8
CLT
4x = -2
Divide both sides by 4
x = -2
4
x = -1

In this question, it is given that
A certain bacteria culture grows at a rate of 18% everyday. There are currently 420 bacteria.
And we have to find number of bacterias on day *.
For that we use the following formula


Substituting these values in the formula, we will get

THerefore on day 8, number of bacterias are 1579.
