Well, if we're looking for the value of "x" then follow these following steps! 

Our first step: 9(x) - [-7] = ?
 The "?" = 0 

Our second step 2: Solve this one → 9(x) = ? 
Remember that I said "?" equals to 0 

Our  third step: we have to divide by the number "9" on each of your sides

Our fifth step/your answer is:  x = 0 

Oh and if you wanted to find out how many solution that it has, it would be One Solution 

There's not that much steps to this solution

<span>9x-7=-7 
You would add 7 to both sides because you want to get to the point were your variable is alone. 9x = 0 Then you would dicide each side by 9 because after doing this your variable would be alone. x = 0 would be your final answer.

0.66666667 as a fraction
Ierofanga [76]

Answer:

__________________________________________

    The correct answer is:   " \frac{2}{3} " .

__________________________________________

Note:  Let's assume that this given decimal value  is really:

"0.66666666666666666....."  ;

(non-terminating; but repeating the singing digit, "7" ; yet rounded to:

" 0.66666667 " ;  

then:  " 0.666... "    = \frac{666}{999}  ;

                             

                               =  (666 ÷ 111) / (999 ÷ 111)  ;

                               =  6/9 ;

                              = (6÷3)/(9÷3)  ;

                               =   2/3 ;

                             

                               =   " \frac{2}{3} "

 

                              →  which is our answer.

____________________________________________

 Or:   " 0.6666... "  =  666 ÷ 999 = ?  ;

                        using calculator :

                               =  0.66666667 ;  

        →  which is the "rounded off" number of "0.6666..." ;

                                                                — (infinitely repeating) ;

                  →   So 666 ÷ 999 =

                  →   "  \frac{666}{999} " ;

               

                               =  " \frac{2}{3} " ;  

                               →  Either use a "fraction calculator" ;

       or simplify as aforementioned.    

____________________________________________

Hope this answer is helpful to you!

The 3 sides of a triangle have lengths of (4x+3) cm, (2x+8) cm, and (3x-10) cm. What is the length of the shortest side if the p
galina1969 [7]

Answer:

The shortest sides is 3x-10

Step-by-step explanation:

This is because if you do the algebra which is 4x+3+2x+8+3x-10=136, x=15. Now that you have 15 you plug it into each sides x value. First, 4x+3= 4*15+3=63

Second, 2x+8=30+8=38

Lastly, 3x-10=45-10=35

So, as you can see here 35 is the lowest value which means the side (3x-10) is the shortest.

<u>To find the density:</u>

 ⇒ must find the relationship between the density, mass, and volume

    ⇒ Density = \frac{mass}{volume}

<u>Let's examine the information given:</u>

  • weight: 1890g
  • dimensions: 8cm * 5cm* 5cm

<u>Let's first find the volume:</u>

   ⇒ the volume is the dimensions multiplied together

      Volume = 8cm * 5cm * 5cm = 200cm^3

<u>LEt's calculate the density now:</u>

  Density = \frac{1890g}{200cm^3} =9.45g/cm^3

<u>Answer:</u> The density of the copper is <u>9.45g/cm^3</u> or <u>Choice (A)</u>

<u></u>

Hope that helps!
