Answer:

x/2 + x = 30 -> $2.50

20/2 + 20 = 30

X = 20, therefore:

dimes = 20

nickels = 10

Two angles are complimentary. One angle measures 69 degrees. The other measures ( 5n + 1). What is the value of n?
iren [92.7K]

Answer:

Step-by-step explanation:

complimentary angles, when added = 90 degrees

69 + 5n + 1 = 90

5n + 70 = 90

5n = 90 - 70

5n = 20

n = 20/5

n = 4 <====

Find the slope of the line passing through the points (-6-9) and (9,-9)
Otrada [13]

9514 1404 393

Answer:

  • zero
  • undefined

Step-by-step explanation:

The slope formula is useful for this.

  m = (y2 -y1)/(x2 -x1)

__

<u>First line</u>:

  m = (-9 -(-9))/(9 -(-6)) = 0/15 = 0

The slope of the first line is zero.

__

<u>Second line</u>:

  m = (-5-1)/(4 -4) = -6/0 = undefined

The slope of the second line is undefined.

_____

It is always a good idea to apply a little critical thinking to the given information. Here, you observe that the y-coordinates of the first pair of points are the same. That means this is a horizontal line, with a slope of 0.

Similarly, you observe that the x-coordinates of the second pair of points are the same. That means this is a vertical line, with undefined slope.

Triangles A and B are similar.<br> If the slope of Y is 4/5 what's the slope of x?
sdas [7]
Similar triangle Hypotenuse must have similar slopes. If you'll notice, y & x are parallel lines, so they will have equivalent slope

In short, Your Answer would be 4/5

Hope this helps!
