Answer:

x = \frac{k -c}{8}

Step-by-step explanation:

8x + c = k\\\\8x + c-c = k -c \ \ \ \ \ \ \ \ \ [\ subtract \ c \ from \ both \ sides \ ]\\\\8x = k - c\\\\\frac{8x}{8} = \frac{k-c}{8} \ \ \ \ \ [ \ divide \ both \ sides\  by\  8 \ ]\\\\x = \frac{k-c}{8}

<em>Identify</em>

8x + c = k

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. [Subtraction Property of Equality] Subtract <em>c</em> on both sides:                         8x = k - c
  2. [Division Property of Equality] Divide 8 on both sides:                                 x = (k - c)/8

for a store contest four out of every 65 people who visit the store will receive a free DVD if 455 people visit the store how ma
Otrada [13]

If the rate at which they are giving the DVDs is the same then it is 4/65 or 16.25% or 0.1625.

Now just multiply 455 by the rate (4/65 or 16.25% or 0.1625) to find how many DVDs were given.

455 × (4/65) = 28

28 DVDs were given away

hope it helps :)

Solve the equation <br>8(4- x) = 7x + 2<br>x=​
Jet001 [13]

Answer: x=2

Step-by-step explanation:

Expand.

32−8x=7x+2

Add 8x to both sides.

32=7x+2+8x

Simplify  7x+2+8x7x+2+8x  to  15x+215x+2.

32=15x+2

Subtract 22 from both sides.

32−2=15x

Simplify  32−2  to  30.

30=15x

Divide both sides by 15.

30/15=x

Simplify 30/15 to 2

2=x

Switch sides.

x=2

Hi I really need help with this question please,
Mrrafil [7]

Answer:

{ ( \sqrt{30 - x} )}^{2}  =  {x}^{2}  \\ 30 - x =  {x}^{2}  \\  \\  {x}^{2}   +  x - 30 = 0 \\ delta = 1 - 4 \times ( - 30) \times 1 = 121 \\ x1 =  \frac{ - 1 +  \sqrt{121} }{2 \times 1}  =  \frac{ - 1 + 11}{2}  = 5 \\ x2 =  \frac{ - 1  -   \sqrt{121} }{2 \times 1}  =  \frac{ - 1  -  11}{2}  =  - 6 \\
