Evaluate (3x-y)/(3(x-y)) if x = 5 and y = 3. *

Mathematics
1 answer:
mel-nik [20]3 years ago
5 0

Answer:

2

Step-by-step explanation:

Write the equation

\frac{3x-y}{3(x-y)}

Add the variables

\frac{3(5)-3}{3(5-3)}

Multiply 3 x 5

\frac{15-3}{3(5-3)}

Subtract the parentheses

\frac{15-3}{3(2)}

Subtract the numerator

\frac{12}{3(2)}

Reduce the fraction with 3

\frac{12}{3(2)} = \frac{4}{2}

Reduce the fraction again with 2

\frac{4}{2} = 2

And there's your answer of 2!

Five more than the quotient of a number and 3 equals 2.
MakcuM [25]

Answer:

\large\boxed{\dfrac{n}{3}+5=2\ or\ n:3+5=2}

Step-by-step explanation:

\dfrac{n}{3}+5=2\\\\\dfrac{n}{3}-\text{the quotient of a number}\ n\ \text{ and 3}\\\\...+5-\text{five more than}

If you want a solution:

\dfrac{n}{3}+5=2          <em>subtract 5 from both sides</em>

\dfrac{n}{3}+5-5=2-5

\dfrac{n}{3}=-3            <em>multiply both sides by 3</em>

3\!\!\!\!\diagup\cdot\dfrac{n}{3\!\!\!\!\diagup}=(3)(-3)\\\\n=-9

The expression ax2-bx=0 is? and has the solution x=0
LUCKY_DIMON [66]
Lets analyze the equation:
<span>ax^2 - bx = 0
</span>x(ax - b) = <span>0
</span>Therefore if x = 0, the equation holds no <span>matter about a and b</span>:
0(0a - b) = 0
0 = 0

What is the distance points for (2,-2) and (0,-9)
Ksivusya [100]

The distance between two points (2,-2) and (0,-9) is 7.3 units, which is obtained by graphical method and formula method.

Step-by-step explanation:

The given is,

         Two points are (2,-2) and (0,-9)

Step:1

         By graphical method,

         For two points (2,-2) and  (0,-9)

                  First point (2,-2)

                             The values of x=2 and y=-9 noted in the graph

                  Second point (0,-9)

                              The values of x=0 and y=-9 noted in the graph

                  Now join the two points, measure the distance between the two points,

                   Distance between points are 7.3 units.

                                          ( OR )

Step:1

        By formula method,

              Distance =   \sqrt{(x_{2}- x_{2})  ^{2}+ (y_{2}-y_{1})  ^{2}  }

       Where,

               ( 2,-2) are (x_{1},y_{1})

               (0,-9) are (x_{2},y_{2})

       From the values,

                             = \sqrt{(0- 2)  ^{2}+ (-9+2)  ^{2}  }

                            =  \sqrt{(- 2)  ^{2}+ (-7)  ^{2}  }

                            = \sqrt{4+49  }

                            = \sqrt{53}

                            = 7.280

                            ≅ 7.3

            Distance = 7.3

Result:

           The distance between two points (2,-2) and (0,-9) is 7.3 units, which is obtained by graphical method and formula method.
