Three numbers have a sum of 68. The second number is 1 less than twice the first. The third number is three times the second. Wh
Vesnalui [34]

Answer:

First number: 71/7

Second number: 135/7

Third number: 270/7

Step-by-step explanation:

First number = x

Second number= 2x-1

Third number= 2(2x-1)

x+(2x-1)+2(2x-1)= 68

3x-1+4x-2=68

7x-3=68

7x=71

x=71/7

You can check by plugging in the x into the equation.

Find the distance between (-4,3,-6) and the origin ((X,Y,Z) Graph)
devlian [24]

The distance between  (-4,3,-6) and the origin is \sqrt{61

<h3>How to determine the distance?</h3>

The point is given as:

(x, y, z) = (-4,3,-6)

The origin is

(x, y, z) = (0,0,0)

The distance between the point and the origin is calculated as:

d = \sqrt{x^2 + y^2 + z^2

So, we have:

d = \sqrt{(-4)^2 + (3)^2 + (-6)^2

Evaluate

d = \sqrt{61

Hence, the distance between  (-4,3,-6) and the origin is \sqrt{61
