The equation of this line in slope intercept form is y= 3/7x
Well knowing that it is divided into 18 EQUAL parts, and the fact that the total number of degrees in a circle is 360.
To find out the number of degrees in each part take 360 and divide that value by 18.
That is the angle measure for each particular part.
Answer:
a: a number is odd
Step-by-step explanation:
It uses the word IF
Let's say p is the principal cost of the total (original) we can setup the equation p-.4p=40.5 => .6p=40.5 => p=67.5
So the cost without the sale is $67.50
For the original price of each pair divide this by 3.
67.5/3=22.5
Final answer:
Each pair costs $22.50 without the sale.
