The sum of 13 divided by a number and that number divided by 13

7nadin3 [17]

Sum means add

the number is x

13 divided by a number is 13/x
the number divided by the number is x/13

so
$\frac{13}{x}+\frac{x}{13}$
also can be simplified to
$\frac{169}{13x}+\frac{x^2}{13x}$ or
$\frac{x62+169}{13x}$

translated it is $\frac{13}{x}+\frac{x}{13}$ where x is the number

Drag numbers to the table so it shows a proportional relationship between x and y.

dezoksy [38]

Answer:

7.5 30

45 180

Step-by-step explanation:

The given line has x = 1.25 and y = 5.

y/x = 5/1.25 = 4

x is multiplied by 4 to get y since 1.25 * 4 = 5.

That means the equation is

y = 4x

For a proportional function, every value of x must be multiplied by 4 to get y.

x = 7.5

y = 4x = 4(7.5) = 30

7.5 30

We need to find the values for the last line.

11 * 4 = 44

There is no 44

13.75 * 4 = 55

There is no 55.

17.5 * 4 = 70

There is no 70

30 * 4 = 120

There is no 120.

45 * 4 = 180

There is a 180.
