If x+1/x = 5 find the value of x^3 +1/x^3. pls solve

Korolek [52]

Answer:

1) solve x+1/x = 5

$\frac{x + 1}{x} = 5$

$x + 1 = 5x$

$x - 5x = - 1$

$- 4x = - 1$

$x = \frac{ -1}{ - 4}$

$x = \frac{1}{4}$

2) solve x³+1/x³

$x {}^{3} + \frac{1}{x {}^{3} }$

substitute x = 1/4 into the expression

$( \frac{1}{4} ) {}^{3} + \frac{1}{( \frac{1}{4}) {}^{3} }$

$\frac{1}{64} + \frac{1}{ \frac{1}{64} }$

$\frac{1}{64} + \frac{64 \times 1}{1}$

$\frac{1}{64} + 64$

$\frac{4097}{64} \: or \: 64.02$

The manager of a fashionable restaurant open Wednesday through Saturday says that the restaurant does about 29 percent of its bu

RideAnS [48]

Answer: The seasonal relatives is calculated are as follows:

Step-by-step explanation:

Given that,

restaurant only open from Wednesday to Saturday,

29 percent of its business on Friday
31 percent on Saturday night
21 percent on Thursday night.

∴ The remaining 19% of its business he does on Wednesday

Now, suppose that total production of sales in a given week be 'y'

So, average sales in a week = $\frac{y}{4}$

If we assume that y = 1

hence, average sales in a week = $\frac{1}{4}$

= 0.25

Now, we have to calculate the seasonal relatives,

that is,

= $\frac{Sales in a given day}{average sales in a week}$

Wednesday:

= $\frac{0.19}{0.25}$

= 0.76

Thursday:

= $\frac{0.21}{0.25}$

= 0.84

Friday:

= $\frac{0.29}{0.25}$

= 1.16

Saturday:

= $\frac{0.31}{0.25}$

= 1.24

Which equation is equivalent to 2x+4a=10 A. X= 5/4a B.5+2a C. X=10-4a D. X=5-2a

kifflom [539]

Alright, so we start off my subtracting 4a from both sides, separating the x and getting 10-4a=2x. Next, we divide both sides by 2, getting that 5-2a=X
