Sunny earns $12 per hour delivering cakes. she worked for x hours this week. unfortunately, she was charged $15 for a late delivery on tuesday. how much money did sunny earn this week? write your answer as an expression.

12x-15

Step-by-step explanation:

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

the least common denominator is 40
