Number n is 25 less than 120% of itself. What is the value of n?
BARSIC [14]

Answer:

n = 125

Step-by-step explanation:

<u>Step 1:  Convert words into an expression</u>

Number n is 25 less than 120% of itself. What is the value of n?

25 less than 120% of itself can be represented as:  <u>1.2n - 25</u>

n = 1.2n - 25

<u>Step 2:  Add Subtract 1.2 from both sides</u>

n - 1.2n = 1.2n - 25 - 1.2n

-0.2n = -25

<u>Step 3:  Divide both sides by -0.2</u>

-0.2n / -0.2 = -25 / -0.2

<em>n = 125</em>

<em />

Answer: n = 125

PLEASE HELP ME 40 PTS!!!!!!
SSSSS [86.1K]

Answer:

The sequence converges to  infinity.

Step-by-step explanation:

a_n = \frac{n^3 - n}{n^2 + 5n}\\\\ \lim_{n \to \infty} a_n  =  \lim_{n \to \infty} \frac{n^3 - n}{n^2 + 5n}

                = \lim_{n \to \infty} \frac{n(n^2 - 1)}{n(n + 5)} \\\\= \lim_{n \to \infty} \frac{(n^2 - 1)}{(n + 5)}\\\\= \lim_{n \to \infty} \frac{n(n - \frac{1}{n})}{n(1 + \frac{5}{n})}\\\\= \lim_{n \to \infty} \frac{(n - \frac{1}{n})}{(1 + \frac{5}{n})}

denominator =  \lim_{n \to \infty}  1 + \frac{5}{n} = 1 +  \lim_{n \to \infty} \frac{5}{n} = 1+0 = 1

numerator =  \lim_{n \to \infty} n - \frac{1}{n} = \infty

Therefore,

             \lim_{n \to \infty} a_n  = \frac{ \infty}{1} = \infty

Plz help? <br><br> Find the value of x in this proportion.<br> 621=10x
sergij07 [2.7K]

Answer:

x = 62.1

Step-by-step explanation:

Note the equal sign in this equation, what you do to one side, you do to the other. Isolate the variable, x, by dividing 10 from both sides of the equation:

621 = 10x\\\\\frac{621}{10} = \frac{10x}{10}  \\\\x = \frac{621}{10} \\x = 62.1
