Solve -11 - x + = - 5 (2x-3) + 7
garri49 [273]

Answer:

Let's see what to do buddy...

Step-by-step explanation:

_________________________________

- 11 - x =  - 5(2x - 3) + 7

- 11 - x =  - 10x + 15 + 7

- 11 - x =  - 10x + 22

Subtract the sides of the equation plus<em> </em><em>1</em><em>1</em> :

- x =  - 10x + 22 + 11

- x =  - 10x + 33

Subtract the sides of the equation plus <em>1</em><em>0</em><em>x</em>

10x - x = 10x - 10x + 33

9x = 33

Divided the sides of the equation by <em>9</em><em> </em>

\frac{9}{9}x =  \frac{33}{9} \\

x =  \frac{33}{9} =  \frac{3 \times 11}{3 \times 3} =  \frac{11}{3} \\

And we're done.

Thanks for watching buddy good luck.

Adhy, Ben and Clayson shared a bag of chocolates. The ratio of Adhy's share to Ben's share is 3:4 while
Ira Lisetskai [31]

Answer:   33

<u>Step-by-step explanation:</u>

The ratio of Adhy's to Ben's is 3:4 so let

Adhy = 3x

Ben = 4x

Since Ben = Adhy + 9

then   4x   =    3x    + 9

-->        x    =  9

So, Adhy = 3x  = 3(9)   = 27

     Ben   = 4x   = 4(9)   = 36

*************************************************************

The ratio of Ben's to Clayson's is 3:5

How do we get Ben's ratio of 3 equal to 36? <em>by multiplying by 12</em>

Ben  :  Clayson

<u>3 x 12</u>    <u>5 x 12</u>

 36          60

So, Clayson = 60

***********************************************************

The difference between Adhy and Clayson is:

Clayson - Adhy

   60     -    27    = 33

Consider the equations y = √x and y = x^2 - 1
lord [1]
<h3>Answer:</h3>

(x, y) ≈ (1.49021612010, 1.22074408461)

<h3>Explanation:</h3>

This is best solved graphically or by some other machine method. The approximate solution (x=1.49, y=1.221) can be iterated by any of several approaches to refine the values to the ones given above. The values above were obtained using Newton's method iteration.

_____

Setting the y-values equal and squaring both sides of the equation gives ...

... √x = x² -1

... x = (x² -1)² = x⁴ -2x² +1 . . . . . square both sides

... x⁴ -2x² -x +1 = 0 . . . . . polynomial equation in standard form.

By Descarte's rule of signs, we know there are two positive real roots to this equation. From the graph, we know the other two roots are complex. The second positive real root is extraneous, corresponding to the negative branch of the square root function.
