2) -2(7n – 6) +n=-3 - 8n
iogann1982 [59]

<em>Answer and Step-by-step explanation:</em>

<em>For this equation the answer is : n=3</em>

<em>Step 1 : Simplify both the sides of the equation :</em>

<em>-2(7n-6)+n=-3-8n</em>

<em>(-2)(7n)+(-2)(-6)+n=-3+-8n   (Distribute)</em>

<em>-14n+12+n=-3+-8n</em>

<em>(-14n+n)+(12)=-8n-3   (Combine the like terms)</em>

<em>-13n+12=-8n-3</em>

<em>-13n+12=-8n-3</em>

<em>Step 2 : Add "8n" to both the sides :</em>

<em>-13n+12+8n=-8n-3+8n</em>

<em>-5n+12=-3</em>

<em>Step 3 : Subtract "12" from both the sides :</em>

<em>-5n+12-12=-3-12</em>

<em>-5n=-15</em>

<em>Step 4 : Divide both the sides by "-5"</em>

<em>\frac{-5n}{-5} =\frac{-15}{-5}</em>

<em>n=3</em>

<em />

<em>That's your final answer : n=3</em>

3.Solve for the the values of x by factoring
k0ka [10]

Answer:

x = 8 ; x = -3

Step-by-step explanation:

Sum = -5

Product = - 24

Factors = 3 , (-8)

x² - 5x - 24 = 0

x² - 8x + 3x - 3 * 8 = 0

x(x - 8) + 3(x - 8)= 0

(x - 8)(x + 3) = 0

x - 8 = 0           ;  x + 3 = 0

   x = 8             ; x  = -3

Taya2010 [7]

Answer:

4310 in all

2750 went to Hartville charity

Step-by-step explanation:

they collected 3,288 one week then 1,022 the next.

so then you add them up

3,288 + 1,022 = 4310

then they donated 1,560. so then you subtract.

4,310 - 1,560 = 2,750
