Answer:
x = 
Step-by-step explanation:
Using the rule of logarithms
log x - log y = log (
)
x = n ⇒ x = 
Given
(9x) - 3 = 3
(
) = 3
3x = 3
3x = 2³ = 8 ( divide both sides by 3 )
x =
Answer:
30
Step-by-step explanation:
Given the equation;
n/10 + 7 = 10
We are to find the value of n
Subtract 7 from both sides
n/10 + 7 - 7 = 10 - 7
n/10 = 3
Cross multiply
n = 10 * 3
n = 30
<em>Hence the solution to the equation is 30</em>

First you change .135 into 135/1000 which can then simplify into 27/200.
In ΔABC,
tanA = a/b
∴ a = b×tanA = 12×1/√3 = 6.928 ~ 6.93 m
