Simplify (1/36)^n=216^n+5

Mathematics
1 answer:
Amanda [17]3 years ago
5 0

Answer: - 2

Step-by-step explanation:

(1/36)^n = 216^n+5

(1/6^2)^n = (6^3)^n+5

(6^-2)^n = (6^3)^n+5

Opening the brackets

6^-2n = 6^3n+15

-2n = 3n + 15

collecting like terms

-2n - 3n = 15

-5n = 15

divide both sides by - 5

n = 15/-5

n = - 3

Find the value of x. 3x, 2x, 55
SOVA2 [1]

The sum of the measures of the angles in a triangle is 180°.

Therefore we have the equation:

2x° + 3x° + 55° = 180°

5x° + 55° = 180°    <em>subtract 55° from both sides</em>

5x° = 125°     <em>divdie both sides by 5</em>

x° = 25°

<h3>Answer: x = 25</h3>

On a bicycle, Esmeralda rides for 2 hours and is 12 miles from her house. After riding for 9 hours, she is 47 miles away.
In-s [12.5K]

For this case what we must do is find the speed of Esmeralda.

For this, we look for the rate of  change of the function

We have then:

AVR=\frac{y2-y1}{x2-x1}

Substituting values:

AVR=\frac{47-12}{9-2}

Rewriting:

AVR=\frac{35}{7}

AVR = 5

Answer:

Esmeralda's average rate during her trip is 5 miles per hour.
