You got 9 right, because 5x -3y = 36
For you to lose points, having answered all of thee questions, to the point of which you were given 36 out of 60 possible points tells that you must have gotten over half right for points to have been taken away, and the only factors that satisfy the equation with those restrictions would determine that x must equal 9, making the amount you got right worth 45 points, but with y equal to 3, 9 points were taken away from that score, making it 36. This can also be displayed on a x versus y graph.

the answer is nine because 9times 5 equals 45 subtract 9 equals 36

A book costs $25 .Marilyn bought the book during a sale with 15% discount. How much did she pay for the book
belka [17]
Original cost of the book = $25
Percentage of discount got by Marilyn while buying the book = 15%
Amount of discount got by Marilyn while buying the book =  (15/100) * 25
                                                                                            = 375/100
                                                                                            = 3.75 dollars
So
The amount paid by Marilyn for buying the book = (25 - 3.75) dollars
                                                                              = 21.25 dollars
<span>So the total amount paid by Marilyn for buying the book is $21.25. I hope the procedure for doing this problem is clear to you.</span>

PLLZZZ HELP QUICK <br> Answer both please
saw5 [17]

Answer:

The Median is the middle number in the sequence.

Because there is an even amount of numbers, you will get two Medians (32,33). Add them together and divide by two (65/2 = 32.5).

The Median is 32.5.

The Range is the what you get when you subtract the lowest number from the highest number (65 - 29 = 36).

The Range is 36.
