Solve for the variable 7/28 = 25/?

ICE Princess25 [194]

Let x be the unknown number. The equation is going to be 7/28=25/x, now we cross multiply. 7*x=25*28, 7x=700, divide both sides by 7 and you should get 100, So, x=100 and 7/28=25/100

ELEN [110]

Answer:

$\boxed{ \mathrm{y = \ negative \ 3 x + 3}}$

Step-by-step explanation:

The coordinates are (-6,0) and (-8,6)

<u><em>Finding slope of the line</em></u>

Slope = $\frac{rise}{run} = \frac{y2-y1}{x2-x1}$

Slope = $\frac{6-0}{-8+6}$

Slope = $\frac{6}{-2}$

Slope = -3

Parallel lines have equal slopes.

So, the line which is parallel to this line is y = negative 3 x + 3

Simple, finding markdown, use these two formulas.

Markdown=Original-New
and
Percent Markdown= Markdown Amount/Original*100

So,

Markdown=612-450
M=162

Markdown%= 162/612*100
M%=0.2647*100
M%=26.5 (rounded)

Thus, there was a 26.5% decrease.
