Solve for X please!!!!!!!!!!!!! I need this answer ASAP<br><br> 2x + 1/3x = 21
Trava [24]
<h2>x = 9</h2><h3 />

<u>We know:</u>

  • we can add/subtract the same expression to both sides of the equation to get an equivalent equation;
  • we can multiply/divide both sides of the equation by the same non-zero number to get the equivalent equation.

<u>Equivalent equations</u> are algebraic equations that have identical solutions.

We have the equation:

2x+\dfrac{1}{3}x=21

<h3>SOLUTION:</h3>

<em>multiply bot sides by 3</em>

<em />3\cdot2x+3\!\!\!\!\diagup\cdot\dfrac{1}{3\!\!\!\!\diagup}x=3\cdot21\\\\6x+x=63\\\\7x=63

<em>divide both sides by 7</em>

<em />\dfrac{7\!\!\!\!\diagup x }{7\!\!\!\!\diagup}=\dfrac{63}{7}\\\\\boxed{x=9}

11-16
GarryVolchara [31]

Answer:

See below in bold.

Step-by-step explanation:

To do these we add or subtract 360 degrees or 2 pi radians. Sometimes multiple actions are required.

11.  Adding  360 to -545:

= -185

185 + 360 = 175

The other angle is 185 degrees so they are not coterminal.

12.  161pi/36 - 2pi

= 161pi /36 - 72pi/36

= 89pi/36

89pi/36 - 72pi/36

= 17pi/36.

So these are coterminal.

13. -330 + 360 = 30 degrees.

14. -435 + 360

= -75

-75 + 360

= 285 degrees

15.  640 - 360 = 280 degrees.

16. -442 + 360 = -82

-82 + 360 = 278 degrees.

Which line best models line one?
kondaur [170]

Answer:

A

Step-by-step explanation:

The equation of a vertical line parallel to the y- axis is

x = c

where c is the value of the x- coordinates the line passes through.

Here the line passes through all points with an x- coordinate of 4, thus

x = 4 → A
