Estimate each sum or difference to the nearest whole numbers. then calculate the exact sum or .02-15.27-3.76

38.99

Step-by-step explanation:

58.02 - 15.27 = 42.75

42.75 - 3.76 = 38.99

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)
