Answer:
Step-by-step explanation:
The midpoint of two coordinates (x1, y1) and (x2, y2) is expressed as;
M(X,Y) = {(x1+x2)/2, (y1+y2)/2}
Given the points A(h, k) and B(h,j)
x1 = h, y1 = k, x2 = h, y2 = j
Substitute into the formula;
M(X,Y) = {(x1+x2)/2, (y1+y2)/2}
M(X,Y) = {(h+h/2, (k+j)/2}
M(X,Y) = {(2h)/2, (k+j)/2}
M(X,Y) = {h, k+j/2}
hence the coordinates of point M is {h, k+j/2}
Answer:
$62.85
Step-by-step explanation:
Given data
ratio= 10: 7: 5
Total ratio= 10+7+5= 22
Lisa= $20
Her proportion of the ratio = 7
Applying the part to all method
Let the total amount shared be x
7/22= 20/x
cross multiply
7x= 22*20
7x= 440
divide both sides by 7
x= 440/7
x= 62.85
I’m guessing 283 because 5x50 equals 250 so $4.15-$2.50 equals $1.65 so $1.65 divided by 5 equals .33 so 33. 33 plus 250 equals 283.
