<u>Answer:</u>

The solution of −3/8÷−6/7 is \frac{7}{16}

<u>Solution:</u>

The given equation is -\frac{3}{8} \div-\frac{6}{7}

In the above equation we can see that more than one mathematical operator has been used.

To figure out which one to solve first we need to follow the BODMAS rule.

BODMAS mean brackets, of, division, multiplication, addition and subtraction.

To make the calculation simply we will invert one of the fractions. This will make the division operator into a multiplication one.

-\frac{3}{8} \times-\frac{7}{6}

This equation can be simplified as 6 is divisible by 3. Also the negative signs cancel out each other.

\frac{1}{8} \times \frac{7}{2}

On multiplying the remaining terms we get;

\frac{7}{16}

Hence the solution of −3/8÷−6/7 is \frac{7}{16}

Answer:

  (a)  y = −50x + 250

Step-by-step explanation:

In case you don't realize that the graph starts at 250 and decreases by 50 for each increase of 1 in x, you can see if any of the equations match the given points. The only one that does is the first one:

  y = -50x +250

Solve the system of equations 2x+4y+3z=6 5x+8y+6z=4
MaRussiya [10]

Answer:Solution :

{x,y,z} = {-8,52/7,-18/7}  

 

System of Linear Equations entered :

  [1]    2x + 4y + 3z = 6

  [2]    5x + 8y + 6z = 4

  [3]    4x + 5y + 2z = 0

Solve by Substitution :

// Solve equation [3] for the variable  z  

 

 [3]    2z = -4x - 5y  

 [3]    z = -2x - 5y/2  

// Plug this in for variable  z  in equation [1]

  [1]    2x + 4y + 3•(-2x-5y/2) = 6

  [1]    -4x - 7y/2 = 6

  [1]    -8x - 7y = 12

// Plug this in for variable  z  in equation [2]

  [2]    5x + 8y + 6•(-2x-5y/2) = 4

  [2]    -7x - 7y = 4

// Solve equation [2] for the variable  y  

 

 [2]    7y = -7x - 4

 [2]    y = -x - 4/7

// Plug this in for variable  y  in equation [1]

  [1]    -8x - 7•(-x -4/7) = 12

  [1]    -x = 8

// Solve equation [1] for the variable  x  

  [1]    x = - 8  

// By now we know this much :

   x = -8

   y = -x-4/7

   z = -2x-5y/2

// Use the  x  value to solve for  y  

   y = -(-8)-4/7 = 52/7  

// Use the  x  and  y  values to solve for  z  

 z = -2(-8)-(5/2)(52/7) = -18/7  

Solution :

{x,y,z} = {-8,52/7,-18/7}

Factor out the coefficient of the variable 1.7j-3.4
Ad libitum [116K]
Here you would factor out a 1.7 because that is the coefficient in front of the j. When you factor, you are essentially dividing each term by the value you are factoring out
1.7j/1.7=j
-3.4/1.7=-2

So the final answer is 1/7(j-2)

Hope this helps<span />
