I think you will have to divied 60 by 20 so it might be 30 dollars.
I think number 2 is 60 dollars.
Maybe it is 12 dollars and 50 cents.

1.) 60-(20% of 60)
60-(.2 * 60)
60-12
48
The pants are $48
2.)30% of x = 20
.3x = 20
.3x/.3= 20/.3
x = 66.6666666...
The pants were $66.67
3.) 25 + (20% of 25)
25+(.2*25)
25+5
30
The magazine is now $30.

Find a equation for the line below

LenaWriter [7]

Answer:

y = - $\frac{1}{2}$ x - $\frac{13}{2}$

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 5, - 4) and (x₂, y₂ ) = (- 1, - 6)

m = $\frac{-6+4}{-1+5}$ = $\frac{-2}{4}$ = - $\frac{1}{2}$ , thus

y = - $\frac{1}{2}$ x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 1, - 6), then

- 6 = $\frac{1}{2}$ + c ⇒ c = - 6 - $\frac{1}{2}$ = - $\frac{13}{2}$

y = - $\frac{1}{2}$ x - $\frac{13}{2}$ ← equation of line

. What is the difference between a right triangle and a obtuse triangle?

Alex

Answer:

In a right triangle two of these are merged into the same square, so there are only two distinct inscribed squares. However, an obtuse triangle has only one inscribed square, one of whose sides coincides with part of the longest side of the triangle.
