answer below

Step-by-step explanation:

C=5/9(F--32)

9C/5=F--32

F=9C/5 +32

When C=30

F=(9*30/5)+32=9*6+32=54+32=86

F=86

so the answer is 86

hope this helps ^^

Step-by-step explanation:

The question is incomplete, as the graph or points of each city are not given.

So, I will provide a general explanation.

To calculate the equation of line through two points;

Start by writing out the coordinates of the two points.

For instance:

London = (4,6)

Warsaw = (20,10)

This points will be represented as:

(x_1,y_1) = (4,6)

(x_2,y_2) = (20,10)

Calculate the slope (m)

$m = \frac{y_2 - y_1}{x_2 -x_1}$

$m = \frac{10 - 6}{20 - 4}$

$m = \frac{4}{16}$

Simplify

$m = \frac{1}{4}$

The equation is then calculated as:

y = m(x - x_1) + y_1

This gives:

$y = \frac{1}{4}(x - 4) + 6$

Open bracket

$y = \frac{1}{4}x - 1 + 6$

$y = \frac{1}{4}x +5$

Apply the above steps in the original question
