Western state college is 18 years older than southern state. western is also 2 1\2 times as old as southern. how old is each

let's firstly, convert the mixed fraction to improper, and then check what's cooking.

if you wonder why we multiplied by the LCD of 2, is just to do away with the denominators.

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1

practice. practice. practice.
