Question

he equation 9(u – 2) + 1.5u = 8.25 models the total miles Michael traveled one afternoon while sledding, where u equals the number of hours walking up a hill and (u – 2) equals the number of hours sledding down the hill. Which is the value

Answer 1

full question: The equation 9(u – 2) + 1.5u = 8.25 models the total miles Michael traveled one afternoon while sledding, where u equals the number of hours walking up a hill and (u – 2) equals the number of hours sledding down the hill. Which is the value of u?

I couldn't find answer choices, but it doesn't really matter since we can just solve the equation for u, and see which of your solutions match.

start by distributing the 9 into (u-2) using the distributive property. then combine like terms (combine the u terms, and the constants together)

you should have a u-term on the left side, and a constant on the right side.

divide both sides by the coefficient of u to isolate u.
