Answer:

The original price of the item is $28.

Step-by-step explanation:

So to find the original price, we have to divide the sale price by the result of one minus the discount in percentage form.

So:

First convert 25% to a decimal, 0.25.

OP(original price) = 21 ÷ 1 - 0.25 =

1 - 0.25 = 0.75

Solve the equation <br> 2 ( a + 10) = 56
Hatshy [7]
Answer: a = 18

explanation:
2(a + 10) = 56 -> distribute the 2
2a + 20 = 56 -> subtract 20 from both sides
2a = 56 - 20
2a = 36 -> divide both sides by 2
a = 18

What is the slope of the line that contains the point (-1,8) and (5,-4) answer.com?
pshichka [43]
THE SLOPE IS -2



if we have the coordinates of two points on a line, we can find the slope with this formula:
s =  \frac{y2 - y1}{x2 -x1}  =  \frac{y1 - y2}{x1 - x2}
so the slope is
\frac{8 - ( - 4)}{ - 1 - 5}  =  \frac{12}{ - 6}  =  - 2
the answer is -2



good luck
