154 divided by 7 i think
so 22 students per class
Mr. Jones has 22 students per class
Answer:
The solution is x = 1/log(6)
Step-by-step explanation:
Hi there!
First, let´s write the equation:
6ˣ + 2 = 12
subtract 2 at both sides of the equation
6ˣ = 10
apply log at both sides of the equation
log(6ˣ) = log(10) log(10) = 1
Apply logarithm property: log(xᵃ) = a log(x)
x log(6) = 1
Divide both sides by log(6)
x = 1/log(6)
The solution is x = 1/log(6)
Have a nice day!
If it's just the 7 that's repeating, let
<em>x</em> = 0.1777...
Then
10<em>x</em> = 1.777...
100<em>x</em> = 17.777...
100<em>x</em> - 10<em>x</em> = 17.777... - 1.777...
90<em>x</em> = 16
<em>x</em> = 16/90 = 8/45
If both 1 and 7 are repeating, let
<em>x</em> = 0.171717...
Then
100<em>x</em> = 17.171717...
100<em>x</em> - <em>x</em> = 17.171717... - 0.171717...
99<em>x</em> = 17
<em>x</em> = 17/99
