Answer:

$r=\frac{7}{3}$

Step-by-step explanation:

When given the equation

$\frac{r}{72} =\frac{3}{9}$

We must multiply each side by 72 in order to isolate r.

$r =\frac{3}{9}*\frac{7}{1} \\\\r=\frac{21}{9} \\\\r=\frac{7}{3}$

6p+4/6=4p-8/3 please show work and explain in full details

Verdich [7]

6p+4/6=4p-8/3 The goal is to always isolate the variable which in this case is p
First bring 4p to the left by subtracting (opposite operation) 4p from both sides. We are left with 2p+4/6=-8/3. We will continue isolating the variable by bring 4/6 to the right by subtracting it from both sides.
We are left with 2p=-10/3
Then divide (opposite operation) both sides by 2 to get p=-5/3

Find the equation of the line that passes through the points (12,21) and (46,33). V.35r-162

AnnZ [28]

Answer:

the answer is Y=(6/17)X + (285/17)

Step-by-step explanation:

1. Identify the X and Y coordinate of each point.

for example, the first point could be (12,21), therefore X1 = 12 and Y1 = 21 and the second point is then (46,33), therefore X2 = 46 and Y2 = 33

2. to find the equation of the line it is necessary to find the slope.

knowing that the equiation of the slope is M = Y2-Y1/X2-X1 we replace

$m=\frac{33-21}{46-12}=\frac{12}{34}$ and then we simplify the result to $\frac{12}{34}$
