Suppose that y varies inversely with x.Write an equation for the inverse variation Y=4 when x=7
myrzilka [38]

Answer:

If y varies inversely as x, then we write it as:

y = k/x


where k is some constant.


If we multiply both sides of this equation by x we get an equation for k:

k = x*y


We are given that y=4 when x=7, therefore:

k = 7*4 = 28


Put this back into our original equation to get:

y = 28/x

The cost of a train ticket increases by
erastova [34]

It costs $122.4 dollars before the increase.

<h3>How to calculate percentage of a number. Use the percentage formula: P% * X = Y</h3>
  • Convert the problem to an equation using the percentage formula: P% * X = Y.
  • P is 17%, X is 7.20, so the equation is 17% * 7.20 = Y.
  • Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.

Therefore, It costs $122.4 dollars before the increase.

Now use K C F method

K - Keep the first fraction

C - Change  the division operation to multiplication

F- Flip the second number

          = \frac{9}{4} *\frac{2}{1}\\\\= \frac{9}{2}*1\\\\= \frac{9}{2}\\\\= 4 \frac{1}{2}
