The time henry spends commuting to school can be represented by two expressions:
time to school: x − 8y
time from school: 2x − 4y
which expression represents the total time henry spends commuting to and from school each day?
3x − 12y
−7x − 12y
x + 4y
3x + 4y

step-by-step explanation:

total time = time to school + time from school

t = (x − 8y) + (2x − 4y)

combine like terms:

t = 3x − 12y

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
