Answer:
4:45
Step-by-step explanation:
What time after 40 minutes gives you 5:25?
If we go back 40 minutes from 5:25, Sofia left her house at 4:45
7x - 9 < 12
7x < 12 + 9
7x < 21
x < 21/7
x < 3
1/4x + 8 > 11
1/4x > 11 - 8
1/4x > 3
x > 3 * 4
x > 12
solution : x < 3 or x > 12
The answer comes out to be X= -2
