Find z for the following proportion:<br><br><br> z/9= 2/3
serg [7]
Cross multiplication will help find the value of x 
\frac{z}{9} = \frac{2}{3} &#10;&#10;&#10;
9*2=18 
3*z=3z 

Now we have :
3z=18 
Divide both sides by 3 to isolate z 

Final answer: z=6

amid [387]
Percent formula : is/of = % / 100

what percent of 21.5 is 55.04...
% = x....because this is what we r looking for
is = 55.04
of = 21.5
now we sub into the formula
55.04 / 21.5 = x / 100
cross multiply because this is a proportion
(21.5)(x) = (100)(55.04)
21.5x = 5504
x = 5504 / 21.5
x = 256 <== so ur answer is 256%

Two points located on are J(1,-4) and K(-2,8). What is the slope of ?
vodka [1.7K]

Answer:

-4

Step-by-step explanation:

The slope is usually a function of the differences in y divided by the differences in x, and it can be described in the following equation,

Slope = \frac{y_{1} - y_{2} }{x{1} - x{2}}     (1)

We can select any of the two points to be our first point, let's say, J(1,-4) is point 1, so J (x1,y1). In other words, x_1 = 1 and y_1 = -4 and by the same way, for K(-2,8). Therefore, x_2 = -2 while y_2 = 8. By substituting these values in equation 1, we can deduce the following

slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{8 - (-4)}{-2 - 1} = \frac{8 + 4}{-2 - 1} = \frac{12}{-3} = -4
