Evaluate the expression 10−5a+(18−b), where a=2 and b=11. Which THREE expressions will have the same value?

A
28÷(a×2)

B
20+b−(4×a)

C
49−43+(a÷a)

D
30−25+(b−9)

E
50÷a−(b+20)

The three expressions that have the same value is A, C, and D

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)
