the fifth answer is 9 dogs

1.) x < 3

2.) x = 5

3.) 8h = 96

4.) 16 miles

5.) 7 dogs

Step-by-step explanation:

1.) 4x < 12

   x < 3

2.) 4x - 7 = 13

    4x = 20

    x = 5

3.) We don't know her hourly pay, so as stated, that's h. She worked 8 hours, which means 8(hours) times the unknown pay rate would equal 96.

4.) 3m + 3 = 51

    3m = 48

    m = 16

    16 miles

5.) 3m - 21 > 0

    3m > 21

    m > 7

    7 dogs

I hope this helped!
