Solve for x and explain the steps:<br> 3x-6=4(2-3x)-8x

mote1985 [20]

Answer: x = 14/23

Step-by-step explanation:

3x-6=4(2-3x)-8x

3x-6=8-12x-8x --> Expand 4(2-3x)

3x-6=8-20x --> Collect like terms

3x-6+6=8-20x+6 --> Add 6 to both sides, to remove it from the right side

3x=-20x+14

3x+20x=-20x+14+20x --> Add 20x to both sides, to remove it from the left side

23x=14

$\frac{23x}{23}=\frac{14}{23}$ --> Divide both sides by 23

x = 14/23

7. Find the distance between the points (13, 8) and (-12, 6)

Alik [6]

9514 1404 393

Answer:

√629 ≈ 25.08

Step-by-step explanation:

The distance formula is useful for this.

d = √((x2 -x1)² +(y2 -y1)²)

d = √((-12 -13)² +(6 -8)²) = √(625 +4) = √629 ≈ 25.08

The distance between the points is about 25.08 units.
