Answer:
if you take into consideration the run from yesterday,
Joe needs to run at least three more days
y > = 3
if you don't take into consideration the 3 mile run from yesterday,
The answer is
He needs to run 4 or more days toachieve his goal
y > = 4
Step-by-step explanation:
12 miles as a minimum
that means
let x be the total amount of miles ran
x > = 12
Let y be the number of days in which Joe runs
3*y > = 12
y > = 4
