Answer:

n = 15

Explanation :

1/4(2n-8) + 1/3n = 1/2(n+6)                 Distribute

1/2n -2  + 1/3n = 1/2(n+6)                    Combine like terms

5/6n -2 = 1/2(n+6)                               Distribute

5/6n -2 = 1/2n +3                                 Pass 1/2n  to the other side

5/6n - 1/2n -2 = 3                                Combine like terms

1/3n  -2 = 3                                            Pass -2 to the other side

1/3n = 3+2                                           Combine like terms

1/3n = 5                                                 Divide both sides by 1/3

n = 15                                                     and then you will get your answer .

Answer:

N=15

Step-by-step explanation:

Simplify 1/4 (2n-8)

2n-8/4+1/4n=1/2(n+6)

Factor out the common term 2.

2(n-4)/4+1/3n=1/2(n+6)

Simplify  2(n-4)/4 to n-4/2

n-4/2+n/3=1/2(n+6)

Simplify  1/3n to n/3

n-4/2+n/3=1/2(n+6)

Simplify 1/2(n+6) to n+6/2

n-4/2+n/3=n+6/2

Multiply both sides by 6 (the LCM of 2, 3,).

3(n−4)+2n=3(n+6)

7 Expand.

3n−12+2n=3n+18

Simplify  3n-12+2n to  5n-12

5n−12=3n+18

Add 12 to both sides.

5n=3n+18+12

Simplify  3n+18+12  to  3n+30

5n=3n+30

Subtract 3n from both sides.

5n-3n=30

Simplify  5n-3n to 2n.

2n=30

Divide both sides by 22

n= 30/2

Simplify 30/2 to 15.

n=15

n=15

An open box is to be made from a rectangular piece of cardboard which is 12 inches by 20 inches by cutting equal squares from th
levacccp [35]

Answer:

side of the square    x  =  2.43 in

Area of the square   x² =  5.91 in²

Step-by-step explanation:

The piece of cardboard  is

20  in    *      12    in    (rectangle)   we are going to cut four squares each in a corner of that piece then

V(b)  =  ( 12  - 2x )* ( 20 - 2x) *x

V(b)  =  ( 240 - 24x - 40x + 4x² ) *x          V(b)  = ( 240 -  64x  + 4x²)*x

V(b)  = 240x  - 64x²  +  4x³

Taking derivatives both sides of equation

V´(b)  =  240  - 128x  + 12x²

Then    V´(b)  =  0          240  - 128x  + 12x²  = 0

A second degree equation solving we have

12x²  -128x  + 240  = 0     ⇒  3x² - 32x  + 60

x₁,₂  = [ 32 ± √(32)² - 720] / 6    ⇒  x₁,₂  = [ 32 ± 17.44]/6

x₁  =  8.24 in   we dismiss this value since 2 times this value is bigger than one side which is not possible

x₂  =  2.43 in  then the square is  (2.43)² =  5.91 in²

Estimate how many times larger 4 x 10^15 is than 8 x 10^9 in the form of a single digit times an integer power of 10.
netineya [11]

Answer:

5×10⁵

5×10⁶

Step-by-step explanation:

1)

\dfrac{4\cdot 10^{15}}{8\cdot 10^{9}}=\dfrac{40\cdot 10^{14}}{8\cdot 10^{9}}\\\\=\dfrac{40}{8}\cdot 10^{(14-9)}=5\cdot 10^{5}

2)

\dfrac{2\cdot 10^{-5}}{4\cdot 10^{-12}}=\dfrac{20\cdot 10^{-6}}{4\cdot 10^{-12}}\\\\=\dfrac{20}{4}\cdot 10^{(-6-(-12))}=5\cdot 10^{6}
