Answer:

x = 3, y = 6

Step-by-step explanation:

<h3>2x=y. and. x+y=9</h3>

<u>x=y/2</u>

<em>y/2+y=9</em>

<em>y+2y=18</em>

<em>3y=18</em>

<em>y = 6</em>

<em> x= 3</em>

Answer:

  44x +56y = 95

Step-by-step explanation:

To write the equation of the perpendicular bisector, we need to know the midpoint and we need to know the differences of the coordinates.

The midpoint is the average of the coordinate values:

  ((-2.5, -2) +(3, 5))/2 = (0.5, 3)/2 = (0.25, 1.5) = (h, k)

The differences of the coordinates are ...

  (3, 5) -(-2.5, -2) = (3 -(-2.5), 5 -(-2)) = (5.5, 7) = (Δx, Δy)

Then the perpendicular bisector equation can be written ...

  Δx(x -h) +Δy(y -k) = 0

  5.5(x -0.25) +7(y -1.5) = 0

  5.5x -1.375 +7y -10.5 = 0

Multiplying by 8 and subtracting the constant, we get ...

  44x +56y = 95 . . . . equation of the perpendicular bisector

20 is 60% of what number
Lilit [14]

Answer:

33.33

Step-by-step explanation:

60% of 33.33 is 20. 100% of 33.33 is 33.33, therefore 60 percent of 33.33 equals 20.

Solve 2x+y=10<br> 4x+7=40
WITCHER [35]
2x + y = 10 is y = -2x + 10
4x + 7 = 40
     -7       -7
4x = 33
4      4
x = 8.25 
y = -2(8.25) + 10 
y = -6.5 and x = 8.25

 Hope this helps :)
