Susie designed an excersise program for herself. One part of the program requires her to walk between 25 to 30 miles each week. She plans to walk the same distance each day five days a week. What is the range of miles that she should walk each day?
Write and solve a compound inequality that represents the situation and graph the soulution.
I'm not sure but maybe the inequality is 25</x</30. Is this right?

5x, not just x
Are the possible values 5 and 6?
well, five miles a day for five days is indeed 25
and six miles a day for five days is indeed 30
When you finish any of these, you can always check them that way.
and six miles a day for five days is indeed 30
When you finish any of these, you can always check them that way.
25<5x<30, where is x is the number of miles she should walk each day
Divide all three parts by 5 to get:
5<x<6
She should walk between 5 and 6 miles each day.
Divide all three parts by 5 to get:
5<x<6
She should walk between 5 and 6 miles each day.
its
25<5x<30
divide out by 5 so you can get the x by itself then you should come out with
5<x<6
25<5x<30
divide out by 5 so you can get the x by itself then you should come out with
5<x<6
