If a and b are two values, their ratio will be a:b,
Given that,
The cost price of 11 slices = $3.97
To find cost price of 18 slices,
First, find the cost price of 1 slice.
Use ratio property,
cost of 11 slices = 3.97
cost of 1 slices = 3.97/11 = 0.3609

Extrca crediedte What is the slope fourmla for ( 3,8) and (2, -11)
Answers
Answer:
Have such a good day and dont let what other people say get 2 u.
To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .
In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line.
Definition: The rate of a lime descending or increasing.
Slope formula of that is 8-(-11) / 3-2. So 19/1 or is it -19/1? It’s one of them I’m doing it in my head so I don’t have any paper right now.
