3/5 + 7/8 = 59/40 but how do I make it to be equal to 1 19/40
Lera25 [3.4K]
Just subtract 59/40 from 119/40
119/40-59/40=60/40
=6/4=3/2
So to make 59/40 equal to 119/40, we will add 3/2 to it
59/40+3/2=119/40

Write an equation that expresses the following relationship.
ahrayia [7]

Given:

u varies directly with the square of p and inversely with d.

To find:

The equation for the given situation.

Solution:

If y is directly proportional to x, then

y\propto x

If y is inversely proportional to x, then

y\propto \dfrac{1}{x}

It is given that u varies directly with the square of p and inversely with d. So,

u\propto \dfrac{p^2}{d}

It can be written as:

u=k\dfrac{p^2}{d}

Where, k is the constant of proportionality.

Therefore, the required equation is u=\dfrac{kp^2}{d}.

Which statement correctly compares the constants of variation for the graph and the equation below?
Lynna [10]

Answer:

  The equation has a greater constant of variation

Step-by-step explanation:

The graph is of a line through point (0, 0) can be represented by the equation ...

   y = kx

Using the given values for x and y, we see that ...

  3 = k·1

  k = 3 . . . . . the constant of variation for the graph

__

The given fraction can be rewritten as ...

  y = (10/3)x = (3 1/3)x

In this form, the constant of variation is 3 1/3, greater than that of the graph.
