We can just divide the two numbers.

13/20 = 0.65

Where 100% = 1

So 65%

To do this we have to see how many times 20 goes into 100. The answer is 5. So we have to times 13 by 5. The answer is 65%

Find the slope pls thx

Lisa [10]

The gradient formula is (y2-y1)/(x2-x1) aka rise/run, where by (x1,y1) and (x2,y2) are two points on the line.

In this case, the gradient
= -5-(-2))/(2-(-2))
= -3/4

For the inverse variation equation xy = k, what is the constant of variation, k, when x = 7 and y = 3? three-sevenths seven-thir

vova2212 [387]

The value of the constant k when the value of x and y is 7 and 3 respectively in the equation xy=k is 21.

<h3>What is an equation?</h3>

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The value of the constant k when the value of x and y is 7 and 3 respectively in the equation xy=k can be written as,

$xy=k\\\\(7) \times (3 ) =k\\\\k= 21$

Hence, the value of the constant k when the value of x and y is 7 and 3 respectively in the equation xy=k is 21.
