Answer:

n =7

Step-by-step explanation:

(n+1) +1 + (n-1) = value first row

3+ (2n-9) +n = value second row

The value has to be the same

Set the equations equal

(n+1) +1 + (n-1) =3+ (2n-9) +n

Combine like terms

2n+1 = 3n-6

Subtract 2n from each side

2n+1-1 -2n = 3n-6-2n

1 = n-6

Add 6 to each side

1+6 = n-6+6

7 = n

Simplify the polynomial. Then find its value for the given value of the variable.

vekshin1

Answer:

Step-by-step explanation:

Simplified expression:

$3x^3 -x^3 +5x^3-9x^3$

$2x^3 +5x^3-9x^3$

$7x^3 -9x^3$

$-2x^3$

If x = -1, the value of the expression is:

$-2x^3$

$-2(-1^3)$

$-2(-1)$

$2$

Hope this helps!

365x + 125 = 250x + 175

maxonik [38]

First, set up the equation.
365x + 125 = 250x + 175

Second, combine like terms on the same side by subtracting 250x and 125 from both sides.

365x +125 = 250x + 175
-250x -125 -250x -125
__________________
115x = 50

Third, divide both sides by 115 to solve for x.

115x = 50
---- ----
115 115

Fourth, simplify.

x=50/115=10/23 or 0.435
