Find the selling price of a $20 item after a 20% markup.
nevsk [136]

Answer:

$24

Step-by-step explanation:

For a markup, use the formula <em>a = ( 1 + p ) × w. </em>

!!! Remember, <em>a </em>is the selling price, and <em>w </em>is the original price !!!

!!! The <em>p </em>is the percent in decimal form. 20% as a decimal is 0.20 (move the decimal twice to the left) !!!

<em />

Inserting the values, it should look like <em>a = ( 1 + 0.20 ) × 20 </em>

<em>a = 1.20 × 20 </em>

<em>a = 24</em>

<em />

Hence, the new selling price is $24.

Hope this helps! :)

What are the three differences between an inconsistent system and a consistent and independent system. Explan?
RUDIKE [14]
Hey there Mejia021274,
1) Independent systems have exactly one solution:
x + y = 1
x - y = 3
x = 2, y = -1

2) Inconsistent systems have no solutions :
5x + y = 6
5x + y = 10
There is no solution as 5x + y cannot be equal to 6 and 10

3) Consistent systems have a lot of solutions:
x+y = 5 
<span>2x+2y = 10 </span>
<span>A few solutions to this system are (1,4), (2,3), (3,2), (4,1), (5,0), and so on.
</span>
Hope this helps :))

I am having trouble with this problem....
Alexeev081 [22]

There 2 angles are corresponding angles, in which the angle measurements would have the same degree.

Set the two angles equal to each other, and solve for x.

7x - 1 = 8x - 14

Isolate the x. Subtract 8x from both sides, and add 1 to both sides

7x (-8x) - 1 (+1) = -14 (+1)

7x - 8x = -14 + 1

-x = -13

Isolate the x. Divide -1 from both sides

(-x)/-1 = (-13)/-1

x = -13/-1

x = 13

13 is your answer for x.
