6 0

Answer:

10%

Step-by-step explanation:

  1. Set up a proportion: \frac{6}{60} = \frac{x}{100}  
  2. Cross multiply, then divide: 6 × 100 = 600, 600 ÷ 60 = 10
  3. 10/100 = 10%

I hope this helps!

Five times the sum of the digits of a two-digit number is 13 less than the original number. If you reverse the digits in the two
In-s [12.5K]
Let the original 2-digit number be xy.
Because 5 times the sum of the digits is 13 less than the number, therefore
5(x + y) = 10x + y - 13 
5x + 5y = 10x + y - 13
-5x + 4y = - 13             (1)

The number with reversed digits is yx.
Because 4 times the sum of the digits is 21 less than the reversed 2-digit number, therefore
4(x + y) = 10y + x - 21
4x + 4y = 10y + x - 21
3x - 6y = -21
x - 2y = -7
x = 2y - 7                 (2)

Substitute (2) into (1).
-5(2y - 7) + 4y = -13
-10y + 35 + 4y = -13
-6y = -48
y = 8

From (3), obtain
x = 2*8 - 7 = 9

Answers:
The original 2-digit number is 98
The reversed 2-digit number is 89
The difference between the original and the reversed 2-digit numbers is
98 - 89 = 9

Which methods could you use to calculate the y-coordinate of the midpoint of a vertical line segment with endpoints at (0, 0) an
Tcecarenko [31]
The y-coordinate of the midpoint of a line segment is the average of the y-coordinates of the endpoints of the line segment.

This is: call y1 the y-coordinate of one endpoint and y2 the y-coordinate of the other endpoint of the line segment, then the midpoint is [y1 + y2] / 2.

The method, then, is to add the two y-coordinates and divide by 2.

For the vertical line segment with endpoints  (0,0) and (0,15) theprocedure is [0 + 15] / 2 = 15/2 = 7.5, and the result is 7.5

Will bought a new skateboard that was on sale. The original price of the skateboard was $60. The store had marked it down by 20
AlexFokin [52]

We conclude that after the discount and the coupon, Will paid $36 for the skateboard.

<h3>How much did Will pay for the skateboard?</h3>

We know that the original price was $60, and two discounts were applied. One of 20% and other of 25%.

Then the amount that he paid is given by:

P = $60*(1 - 20%/100%)*(1 - 25%/100%)

P = $60*(0.8)*(0.75)  = $36

We conclude that after the discount and the coupon, Will paid $36 for the skateboard.
