N/5+0.6=2 solve for n

Mathematics

Pavlova-9 [17]3 years ago

Well, to solve this problem, you have to isolate x. The first step of doing this is subtracting 0.6 from each side to leave the equation as N/5=1.4. Then, you need to multiply both sides by 5 to find N. N/5*5=N, and 1.4*5=7. That leaves the equation as N=7, so the value of N is 7.
Hope this helps!

The answer is:  " 7 "  . 
_________________________________________________
       →    " n = 7 " .
_________________________________________________

Explanation:
_________________________________________________

Given:  
_________________________________________________
" (n/5) + 0.6 = 2 " ;   Solve for "n" ;

Subtract "0.6" from EACH SIDE of the equation:

(n/5) + 0.6 − 0.6 = 2 <span>−0.6 ; 

to get:

(n/5) = 1.4 ; 

 Multiply EACH SIDE by "5" ; to isolate "n" on one side of the equation; 
                                                & to solve for "n" ;


5 * (n/5) = 1.4 * 5  ;

to get:
__________________________________________
   " n = 7 ".
__________________________________________ 

Method 2)
__________________________________________
</span>Given:  " (n/5) + 0.6 = 2 " ;   Solve for "n" ;<span>
   
Note that we have "fifths" (the "fraction, (n/5)" ;

           </span>→  <span>and:  "10ths" (the decimal, "0.6" = "6/10" ) ; 

Multiply the entire equation (both sides) by "10" ; to get rid of both the "fraction" and the "decimal" ; 

Note:  We choose "10"; since "10" is the highest "fraction" (that is represented by a "decimal value"; that is:  "6/10" ;  {i.e.,  "0.6 = 6/10" ; as aforementioned} ;
                                    </span>→ and since:  "5" is a factor of "10" ; 

So, multiplying the entire equation by "10"; will get rid of both the "fraction" AND the "decimal" values:

   →  10 * { (n/5) + 0.6) } = 2 * (10) ; 
___________________________________________________
Note the "distributive property" of multiplication:___________________________________________________a(b + c) = ab + ac ;
a(b – c) = ab – ac .___________________________________________________As such:  

  →  Consider the  "left-hand side" of the equation:
__________________________________________

   →  10 * { (n/5) + 0.6) } ;
 
                       =    [10 * (n/5) ] + [10 * 0.6] ; 

                       =    (10n / 5) + 6 ; 

                       =    (10/5)n + 6 ;

                       =     2n + 6  ;

So we rewrite the equation:

  →  2n + 6 =  2 * (10) ; 

Let us consider the "right-hand side of the equation: 

 →  2 * (10) = 20 .
________________________________________________
Rewrite the equation as:

  →  2n + 6 =  20 ;

Now, solve for "n" ;
________________________________________________
Variant # 1 ):
________________________________________________
   →  2n + 6 =  20 ;

Subtract "6" from EACH SIDE of the equation; as follows:

   →  2n + 6 − 6 = 20 <span>− 6 ; 

to get:  

   </span>→  2n = 14 ; 

Now, divide each side of the equation by "2" ; 
     to isolate "n" on one side of the equation; & to solve for "n" ;

   →  2n / 2 = 14 / 2 ; 

   →  " n = 7 ".
____________________________________________________
Variant # 1 ):
____________________________________________________
   →  2n + 6 =  20 ;
____________________________________________________
Divide the entire question by "2" ; to simplify; as follows:
____________________________________________________
   →  {2n + 6} / 2 =  20 / 2  ;

  →  (2n/2)  +  (6/2) =  (20/2 ) ; 

  →   n  +  3 = 10  ;

Subtract "3" from EACH SIDE of the equation;
       to isolate "n" on one side of the equation; & to solve for "n" ;

 
    →   n  +  3 − 3 = 10 <span>− 3 </span>; 

to get:

             →    " n = 7 " .

A 42-inch board is to be cut into three pieces so that the second piece is twice as long as the first piece and the third piece
Karo-lina-s [1.5K]

Answer: 7 inches

Step-by-step explanation:

       If x is the first piece, and the second piece is twice as long, then the second piece is 2x.

        If the third piece is three times as long as the first piece, x, then the third piece is 3x.

       The 42-inch board must be equal to all 3 pieces, so we will set up an equation and solve for x.

42 = x + 2x + 3x

42 = 6x

42 = 6x

7 = x

              The first piece is 7 inches long.

A sine function has the following key features: Period = 4 Amplitude = 3 Midline: y=−1 y-intercept: (0,-1) The function is not a
mezya [45]

Answer:

  • See the graphs attached and the explanation below

Explanation:

The most simple sine function, considered the parent function, is:

     y=sin(x)

That function has:

  • Midline, also known as rest or equilibrium position: y = 0
  • Minimum: - 1
  • Maximum: 1
  • Amplitude: the distance between a minimum or a maximum and the midline = 1
  • period: the interval of repetition of the function = 2π

The more general sine function is:

             y=Asin(Bx+C)+D

That function has:

  • Midline: y = D (it is a vertical shift from the parent function)
  • Minimum: - A + D
  • Maximum: A + D
  • Amplitude: A
  • period: 2π/B
  • phase shift: C (it is a horizontal shift of the from the parent function)

Now, you have to draw the sine function with the given key features:

  • Period = 4 ⇒ 2π/B = 4 ⇒ B = π/2
  • Amplitude, A = 3
  • midline y = - 1 ⇒ D = - 1
  • y-intercept = (0, -1)

Substitute the know values and use the y-intercept to find C:

       

            y=3sin(2x/\pi+C)-1

Substitute (0, -1)

             

              -1=3sin(0+C)-1\\ \\ 3sin(C)=0\\ \\ sin(C)=0\\ \\ C=0

Hence, the function to graph is:

              y=3sin(\pi x/2)-1

To draw that function use this:

  • Maxima: 3(1) - 1 = 3 - 1 = 2, at x = 1 ± 4n (n = 0, 1, 2, 3, ...)
  • Minima: 3(-1) - 1 = - 3 - 1 = -4
  • y-intercept: (0, - 1)
  • x-intercepts: the solutions to 0 = 3sin(πx/2) = - 1
  • first point of the midline: (0, -1) it is the same y-intercept

With that you can understand the graphs attached.

in a xy-coordinate system line 1 has a slope of -3. If the points (2,16 and (5,t) are on line 1, what is the value of t?
Dimas [21]
We can use the formula y2-y1/x2-x1 to find our answer. So, we have : t-16/5-2 = -3. We simplify that to t-16/3 = -3. We can then multiply both sides by 3 to get t-16 = -9. Then we can add 16 to both sides to get t = 7.
