How do you do this?!<br> (2w-1)/(4)=(2-w)
nikklg [1K]

Answer:

w = 3 is your answer.

Step-by-step explanation:

You want to get w by itself.

<em>(2w - 1)/(4) = 2 - w         </em><u>You will add the w on both sides.</u>

<em>(3w - 1)/(4) = 2                </em><u>You will multiply 4 on both sides.</u>

<em>3w - 1 = 8                       </em><u>You will add 1 on both sides.</u>

<em>3w = 9                            </em><u>You will divide 3 on both sides.</u>

w = 3 is your answer.

Would appreciate it, if anyone could help with this.
Tema [17]
Since they are intersecting lines, you would equal them to each other.
(5x+4)= (8x-71)
-8x. -8x
-3x + 4 = -71
- 4. -4
-3x = -75
Divide 3x by both sides gets you x = 25

Elanso [62]
We are to solve for the price per unit. Let "x" be the price per unit.
The given values are the following:
 Variable Cost = 1250,000 *x
Fixed Cost = $780,000
Net Profit = $650,000
Variable cost per unit = $19.85

The solution is shown below:
$650,000 = 1,250,000*x - $780,000 - $1,250,000*$19.85
x = $26, 242, 500 / 1,250,000 units
x = $20.994

The price per unit is $20.99 and the answer is letter "D".
