When 50% of a number is added to the number, the result is 195.<br> What is the number?
olasank [31]

Answer:

The required number is 130

Step-by-step explanation:

Let the number be x

Given :-. 50% of a number ( 50% of x ) is added to the number ( x ) the result is 195.

50\% \: of \: x \:  + x = 195 \\  \\  \frac{50}{100}  \times x + x = 195 \\  \\  \frac{1}{2} x + x = 195 \\  \\  \frac{3}{2} x = 195 \\  \\ x = 195  \times  \frac{2}{3}

x = 130 !

How to solve 2x= -x + 3 by graphing
FrozenT [24]

Answer:

  x = 1

Step-by-step explanation:

To find a solution to this by graphing, you would typically make a graph of the expression on the left, and another graph of the expression on the right. Where they intersect is the solution.

You would graph ...

  • y = 2x
  • y = -x +3

You're only interested in the x-value where these lines cross, x=1.

_____

<em>Alternate method</em>

Graph the difference of the left side and the right side:

  y = (2x) -(-x +3)

and look for the value of x that makes y = 0. This, too, gives the solution x=1.

__

Of course, once you have the equation ...

  0 = 3x -3

the solution is pretty obvious. (Divide by 3 to make it more obvious.)
