Answer: improper fraction : x= 29/4

Mixed number: x=  7   1/4

Decimal form: x=  7.25

Step-by-step explanation: <em>* x is the shortened of saying 1x *</em>

  1. Add like terms (out of the equation combine +3x and +1x which is<u><em> 4x</em></u>. And combine +2and  -6 which is <u><em> -4 </em></u>) and now the equation is reads                   4x -4= 25
  2. Move the "-4" to the other side pf the equation by Addition Property of Equality  4x -4 = 25                                                                                              .                   +4    +4                                                                                                    .                 4x    = 29
  3. Then, separate the 4 from the x to get it by itself by Dividing 4 into 4x . *Remember what you do to one side of the equation do to other side*       4x/4 = 29/4                                        
  4. The answer now depends what the teacher wants if she want it to stay as an improper fraction it will be 29/4 if it wanted in Mixed number its   7 and 1/4 and if its necessary to have in decimal form its 7.25.

Answer:

x= 7.25

Step-by-step explanation:

3x+2+x-6=25

Step 1- Add the variables

4x+2-6=25

Step 2- Add to both sides

4x+2-6= 25

       +6   +6

Step 3- Subtract to both sides

4x+2= 31

   -2     -2

Step 4- Divide to both sides

<u>4x</u>=<u>29</u>

4    4

x=7.25

Prove that sinxtanx=1/cosx - cosx
maks197457 [2]

Answer:

See below

Step-by-step explanation:

We want to prove that

\sin(x)\tan(x) = \dfrac{1}{\cos(x)} - \cos(x), \forall x \in\mathbb{R}

Taking the RHS, note

\dfrac{1}{\cos(x)} - \cos(x) = \dfrac{1}{\cos(x)} - \dfrac{\cos(x) \cos(x)}{\cos(x)} = \dfrac{1-\cos^2(x)}{\cos(x)}

Remember that

\sin^2(x) + \cos^2(x) =1 \implies 1- \cos^2(x) =\sin^2(x)

Therefore,

\dfrac{1-\cos^2(x)}{\cos(x)} = \dfrac{\sin^2(x)}{\cos(x)} = \dfrac{\sin(x)\sin(x)}{\cos(x)}

Once

\dfrac{\sin(x)}{\cos(x)} = \tan(x)

Then,

\dfrac{\sin(x)\sin(x)}{\cos(x)} = \sin(x)\tan(x)

Hence, it is proved
