(-2,0) And (a,3) <br> Slope 3/8
UkoKoshka [18]

Answer:

a= 6

Step-by-step explanation:

slope = (y2 - y1)/(x2 - x1)

3/8 = (3 - 0)/(a - (-2))

cross multiplying,

3(a + 2) = 3(8)

3a + 6 = 24

3a = 18

a = 18/3

a = 6

Find the original price of a pair of shoes if the sale price is $40 after a 60% discount
Arturiano [62]

Answer:

<em>Thus, the original price of the pair of shoes was $100.</em>

Step-by-step explanation:

<u>Percentages</u>

After a 60% discount, the sale price is now valued at 100-60=40% of its original price.

If the sale price is $40, then the original price is calculated as

$40 / 40 * 100 = $100

Thus, the original price of the pair of shoes was $100.

Verify applying 60% discount:

$100 - 60*$100/100 =  $40
