Answer:
x = -1/2
Step-by-step explanation:
This question can be solved by applying the laws of indices
In a^n, a - base
n - index
Given
9^x = 1/3
According to the laws of indices, a/b = b^(-a)
Hence we can write, 1/3 = 3^(-1)
9^x = 3^(2x)
Again according to the laws of indices,
a^b = a^n can be written as;
b = n
That is, if in an equation the bases are the same, the indices are also equal.
So we can write,
3^(2x) = 3^(-1)
2x = -1
Divide both sides of the equation by 2, the coefficient of x
2x/2 = -1/2
x = -1/2

Answer: In a week you can travel 941 miles
Step-by-step explanation:
$240+0.15m=$381
Subtract $240 on both sides:
$240-$240+0.15m=$381-$240
0.15m=$141
Divide 0.15 on both sides:
0.15m/0.15=141/0.15
m=941 miles
