Austen and Troy take long walks every evening. Austen walks at a constant speed of 4 miles per hour, and Troy walks at a constant speed of 5 miles per hour. One evening, Austen headed out first, and had already gone 5 miles when Troy started his walk. When they have walked the same distance, how far will they each have walked? Write a system of equations, graph them, and type the solution.

answer: y = -12x + 108

step-by-step explanation: do (y = m x+b) formula.

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

the answer is 21%.
