Today only, a sofa is being sold at a 72% discount. The sale price is 218.40.
EastWind [94]

Answer:

780

Step-by-step explanation:

Let x be the original price

x - x*72% is the new price

x - .72x = 218.40

.28x = 218.40

Divide each side by .28

.28x/.28 = 218.40/.28

x =780

Find the slope of the line with the given equation. Show your work.<br> 6x – 2y = 18
Vera_Pavlovna [14]
Currently the equation 6x - 2y = 18 is in standard form. Convert the standard form equation into a slope-intercept form and we can find the slope easily.

Solve for y.

6x - 2y = 18
-2y        = 18 - 6x <-- Subtract 6x from each side. This is to isolate the 2y term
2y / -2  = \frac{18 - 6x}{2} <-- Divide each side by 2. This it to
                                                               get rid of the 2 coefficient.
y = -9 + 3x

Rearrange the right-hand side a bit.

y = -9 + 3x becomes y = 3x - 9

Now it is in slope-intercept form.
The slope is the coefficient of the x variable.

So, 3 is the slope.
