1/2(x - 3) = 2/3(x - 8)

<em><u>Distributive property on both sides.</u></em>

0.5x - 1.5 = 0.7x -5.3

<em><u>Add 5.3 to both sides.</u></em>

0.5x + 3.8 = 0.7x

<em><u>Subtract 0.5x from both sides.</u></em>

3.8 = 0.2x

<em><u>Multiply both sides by 5.</u></em>

x = 19 (This is your answer.)

Let me know if you have any other questions. :)

Solve x 2 - 4x - 7 = 0 by completing the square. What are the solutions?
Bingel [31]

Answer:

x = 2±sqrt(11)

Step-by-step explanation:

x^2 -4x - 7 =0

Add 7 to each side

x^2 -4x -7+7 =0+7

x^2 -4x =7

To complete the square take the coefficient of the x term and  divide by 2 and then square it.  Add it to both sides

-4 /2 = -2 then square

(-2)^2 = 4

Add 4 to both sides

x^2 -4x+4 =7+4

x^2 -4x+4 = 11

Factor the left side into (x-b/2)^2

(x-2)^2 =11

Take the square root of each side

sqrt((x-2)^2) =±sqrt(11)

x-2 = ±sqrt(11)

Add to to each side

x-2+2 = 2±sqrt(11)

x = 2±sqrt(11)

Abby has been absent from class.how would you explain to her what absolute value is use the number line and an example in yout e
KIM [24]
Alright so if you have a negative number let's say -5 if you put the absolute value symbols around it like so |-5| then it becomes positive. Whatever is in the lines becomes positive, that's why I call it the positive box. It describes the distance of a number on the number line from 0 without considering which direction from zero the number lies. The number is never negative
