Question

Part A Joseph runs 4 miles on Monday. Each day after that he runs the same 2 mile route every morning. His goal is to run at least 10 miles by the end of the week. What inequality represents the least number of days after Monday that Joseph needs to run to reach his goal

Part B what is the least number of days after Monday that Joseph needs to run to reach his goal

Answer 1

Answer: 2x + 4mi >=10 , 3

Step-by-step explanation:
x=days after monday

Since Joseph ran 4 miles the first day, that number stays constant. The 2miles depends on the amount of days he runs for so that is the coefficient. Atleast means greater than or equal to. Using the inequality, we can solve that x >= 3.

2x+4>=10

-4 -4

2x>=6

/2 /2

x>=3
