Answer:

x = 12

Step-by-step explanation:

3x - 1 + x + 7 = 54

4x + 6 = 54

4x + 6 - 6 = 54 - 6

4x = 48

\frac{4x}{4}  =  \frac{48}{4}

x = 12

3(12) - 1 + (12) + 7 = 54

36 - 1 + 12 + 7 = 54

35 + 12 + 7 = 54

35 + 19 = 54

54 = 54

Georgia [21]

Answer:

  • B(2, 4)

Step-by-step explanation:

<u>Given points:</u>

  • A(-1, -9) and M(0.5, -2.5)

Let the coordinates of B are (x, y)

<u>Use midpoint formula to determine the point B:</u>

  • 0.5 = (- 1 + x)/2 ⇒ 1 = -1 + x ⇒ x = 1 + 1 = 2
  • -2.5 = (-9 + y)/2 ⇒ -5 = -9 + y ⇒ y = -5 + 9 = 4
