18.57

Step-by-step explanation:

First you have to simplify the equation using cross-multiplication

You should get 7v=130

Then divide both sides by 7

You should get v=130/7

simplify that and get 18 4/7

Turn that into decimal form and you get 18.57

18.57

Step-by-step explanation:

1. Multiply all terms by the same value to eliminate fraction denominators

v/10 = 13/7

10 x v/10 = 10 x 13/7

2. Simplify

130/7 = 18.571428571429

3. Round to the Nearest Tenth

18.57

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:
