Mr. russo exchanged 200 euros for 270 dollars how many dollar he get foe 300 euros

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)

yes. we do proportions in probabilities.

im pretty sure it would be 5 am, hope that , and give brainliest and guys if this is right then press the button and give 5 stars
