Answer:

  • The number at B is 10.6

Step-by-step explanation:

Let the number at B be x.

We know that distance between two points on the number line is the absolute value of the difference of numbers at those points.

Then distances representing the lengths of segments AB and BC are:

  • AB = x - 9
  • BC = 13 - x

We are given the ratio of segments:

  • AB/BC = 2/3

Substitute and solve for x:

  • (x - 9)/(13 - x) = 2/3
  • 3(x - 9) = 2(13 - x)
  • 3x - 27 = 26 - 2x
  • 3x + 2x = 26 + 27
  • 5x = 53
  • x = 53/5
  • x = 10.6

Solve the system of equations. 4x + 2y = –14 6x + 3y = –22 (0, –7), (–1, –6), no solutions, infinitely many solutions. Plz and T
Marizza181 [45]

Answer:

no solutions

Step-by-step explanation:

4x + 2y = –14

6x + 3y = –22

Divide the first equation by 2 and the second equation by 3

4x/2 + 2y/2 = –14/2     2x +y = -7

6x/3 + 3y/3 = –22/3    2x + y = -22/3

The left hand sides are the same but the right hand sides are different.

Multiply the second equation by -1

2x+y = -7

-2x -y = 22/3

-------------------

0 = -7+22/3

0 = 1/3

This is never true, so there are no solutions
