Subtract 6 from both sides and you get 6=3(2x−10)

Divide both sides by 3 and you get ​6/​​3​​=2x−10 and 6/3=2 so 2=2x−10

then add 10 to both sides    2+10=2x and you get 12=2x divide by 2  

x=6 then check your answer and you get 12=12

Hello.

1. switch sides

3(2x-10)+6=12

2.subtract 6 from both sides

3(2x-10)+6-6=12-6

3. simplfy

3(2x-10)=6

4. divide both sides by 3

3(2x-10)/3=6/3

5. simpfly

2x-10=2

6. add 10 to both sides

2x-10+10=2+10

7 simpfly

2x=12

Answer=6

have a nice day

The hanger image below represent a balanced equation...Find the value of c that makes the equation true.
GarryVolchara [31]

Answer: c = 4

Step-by-step explanation:

For balancing a hanger,

The weight of both sides of the hanger must be equal,

Here, the left side weight = 24 unit,

While the right sides total weight = c + c + c + c + c + c

= 6 c

For balancing it,

6 c = 24

⇒ c = 4

Thus, in the balancing equation the value of c will be 4.

Find the distance of the point (4,4,−4) from the line r(t)=⟨−1+2t,1+2t,3−3t⟩.
Nadusha1986 [10]

Translate the given point and line together so that you get a new point and a new line that passes through the origin. This turns the problem into finding the distance between the new point,

<em>p</em> = (4, 4, -4) - (-1, 1, 3) = (5, 3, -7)

and the new line,

<em>r*</em><em>(t)</em> = <em>r</em><em>(t)</em> - ⟨-1, 1, 3⟩ = ⟨2<em>t</em>, 2<em>t</em>, -3<em>t</em>⟩

Let <em>p</em> = ⟨5, 3, -7⟩, the vector starting at the origin and pointing to <em>p</em>. Then the quantity ||<em>p</em> - <em>r*</em><em>(t)</em>|| is the distance from the point <em>p</em> to the line <em>r*</em><em>(t)</em>.

Let <em>u</em> be such that ||<em>p</em> - <em>r*</em><em>(t)</em>|| is minimized. At the value <em>t</em> = <em>u</em>, the vector <em>p</em> - <em>r*</em><em>(t)</em> is orthogonal to the line <em>r*</em><em>(t)</em>, so that

(<em>p</em> - <em>r*</em><em>(u)</em> ) • <em>r*</em><em>(u)</em> = 0

I've attached a sketch with all these elements in case this description is confusing. (The red dashed line is meant to be perpendicular to <em>r*</em><em>(t)</em>.)

Solve this equation for <em>u</em> :

<em>p</em> • <em>r*</em><em>(u)</em> - <em>r*</em><em>(u)</em> • <em>r*</em><em>(u)</em> = 0

<em>p</em> • <em>r*</em><em>(u)</em> = <em>r*</em><em>(u)</em> • <em>r*</em><em>(u)</em>

and <em>x</em> • <em>x</em> = ||<em>x</em>||² for any vector <em>x</em>, so

<em>p</em> • <em>r*</em><em>(u)</em> = ||<em>r*</em><em>(u)</em>||²

⟨5, 3, -7⟩ • ⟨2<em>u</em>, 2<em>u</em>, -3<em>u</em>⟩ = (2<em>u</em>)² + (2<em>u</em>)² + (-3<em>u</em>)²

10<em>u</em> + 6<em>u</em> + 21<em>u</em> = 4<em>u</em> ² + 4<em>u</em> ² + 9<em>u </em>²

17<em>u</em> ² - 37<em>u</em> = 0

<em>u</em> (17<em>u</em> - 37) = 0

==>   <em>u</em> = 0   or   <em>u</em> = 37/17

We ignore <em>u</em> = 0, since the dot product of any vector with the zero vector is 0.

Then the minimum distance distance between the given point and line is

||<em>p</em> - <em>r*</em><em>(u)</em>|| = ||⟨5, 3, -7⟩ - 37/17 ⟨2, 2, -3⟩|| = √(42/17)
