Mark's dog ran 3 4 of a mile in 1 4 of an hour. Compute the unit rate from the complex fraction 3 4 1 4 miles per hour.
The similarities / characteristics the two cars share
let x be the age of her son
y = 25 + x
y - 25 = x
(y + 12) + (x + 12) = n
y + x + 24 = n
y + y - 25 + 24 = n
2y - 1 = n
sub
2(38)-1 = n
n = 78
