Answer:
x = -5
Step-by-step explanation:
Simplifying
6x + -3(x + -8) = 9
Reorder the terms:
6x + -3(-8 + x) = 9
6x + (-8 * -3 + x * -3) = 9
6x + (24 + -3x) = 9
Reorder the terms:
24 + 6x + -3x = 9
Combine like terms: 6x + -3x = 3x
24 + 3x = 9
Solving
24 + 3x = 9
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-24' to each side of the equation.
24 + -24 + 3x = 9 + -24
Combine like terms: 24 + -24 = 0
0 + 3x = 9 + -24
3x = 9 + -24
Combine like terms: 9 + -24 = -15
3x = -15
Divide each side by '3'.
x = -5

Answer:
The value of b = 1/36
As exponent decreases, each previous value is divided by 6
If the table was extended, the value of 6^-3 would be 1/216
Step-by-step explanation:
Given in the question a table containing power of 6
We will use negative rule of exponent to write the equivalent of negative power of 6
b^{-n}= 1 / b^{n}
we know that
so
= 1/6
and
So,
=
Based on the heights of the summits of Mt. McKinley and Mt. Kosciuszko, we find that Mt. McKinley is higher than Mt. Kosciuszko by 13,000 ft
<h3>What are the heights of Mt. Kosciuszko and Mt. McKinley?</h3>
Mt. McKinley is reputed to be the tallest mountain in the North American continent which makes sense considering it has a summit with the height of 20,310 feet.
Mt. Kosciuszko on the other hand, is not that tall and stands at a height of 7,310 ft and is located in Australia.
The difference between both summits is:
= 20,310 - 7,310
= 13,000 ft
