Which expression is equivalent to (8x – 20) + (-4x + 12)?

A. 12x + 8


B. 4x – 8


C. – 4x – 8


D. – 4x

Answer:

1) solve x+1/x = 5

[tex] \frac{x + 1}{x} = 5[/tex]

[tex]x + 1 = 5x[/tex]

[tex]x - 5x = - 1[/tex]

[tex] - 4x = - 1[/tex]

[tex]x = \frac{ -1}{ - 4} [/tex]

[tex]x = \frac{1}{4} [/tex]

2) solve x³+1/x³

[tex]x {}^{3} + \frac{1}{x {}^{3} } [/tex]

substitute x = 1/4 into the expression

[tex]( \frac{1}{4} ) {}^{3} + \frac{1}{( \frac{1}{4}) {}^{3} } [/tex]

[tex] \frac{1}{64} + \frac{1}{ \frac{1}{64} } [/tex]

[tex] \frac{1}{64} + \frac{64 \times 1}{1} [/tex]

[tex] \frac{1}{64} + 64[/tex]

[tex] \frac{4097}{64} \: or \: 64.02[/tex]

Answer:

Son age be 10

And, the father age be 40

Step-by-step explanation:

The computation of the present ages is shown below:

Let us assume the son age be x

And, the father age be x + 30

Now after five hence, their ages are

Son age = x + 5

And, the father age be = x + 30 + 5

Also the father age is thrice of his son age

So the equation would be

3(x + 5) = x + 35

3x + 15 = x + 35

2x = 20

x = 10

The son age is 10

And, the father age is = 10 + 30 = 40

The correct ans is Five,

Let the son’s present age be x years.

Then the father’s present age is (x+30) years.

Father’s age after 5 years =(x+40) years

Son’s age after 5 years = (x+5) years

(x+40) = 3[x + 5]

x + 40 = 3x + 15

2x = 10

∴ x = 5
