uranmaximum [27]3 years ago
7 0

Answer:

1. x = 24

2. y = 9

3. h = 16

4. r = 15

Step-by-step explanation:

1.

\frac{4}{8}  =  \frac{12}{x}

So 4x = 12 * 8

4x = 96

x = 24

2.

(3/3) = (9/y)

So 3y = 3*9

3y = 27

y = 9

3.

(5/20) = (4/h)

So 5h = 20*4

5h = 80

h = 16

4.

(8/20) = (6/r)

So 8r = 20*6

8r = 120

r = 15

Formulas - Fractions<br> Solve c = 4/5(kp + m)<br> p=
Nostrana [21]

c = 4/5(kp + m)
Divide both sides by 4/5 or multiply by 5/4
5/4c = kp + m
Subtract m from both sides
5/4c - m = kp
Divide by k on both sides
(5/4c - m) / k = p


p = (5/4c - m) / k

What is the equation?
Cerrena [4.2K]

to get the equation of a straight line, all we need is two points, hmmm say this line runs over (0 , -2) and (3 , 0), so let's use those.

\bf (\stackrel{x_1}{3}~,~\stackrel{y_1}{0})\qquad (\stackrel{x_2}{0}~,~\stackrel{y_2}{-2}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-2-0}{0-3}\implies \cfrac{-2}{-3}\implies \cfrac{2}{3} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-0=\cfrac{2}{3}(x-3)\implies y=\cfrac{2}{3}x-2
