10 - x = -8
x = 10 + 8
x = 18

10 - 18 = -8
Answer:
t + 3:45 = 11:20 am
Step-by-step explanation:
A rocket is scheduled to launch from a command center in 3.75 hours.
The launch time is 11:20 am.
We need to know the time before 3.75 hours of 11:20 am.
3.75 hours = 3 hours (0.75 × 60) = 45 minutes
Let the current time be 't'
Now the equation will be
t + 3:45 = 11:20 am
t = 11:20 - 3:45
t = 7 : 35 am
Before 3.75 hours of 11:20 am it will be 7:35 am.
The equation would be 3.75+t=11.2 so:
3.75+t=11.2
3.75+t-3.75=11.2-3.75
t=7.45, which is 7:35.
