Answer:
53.2 mph
Step-by-step explanation:
Mara's family travels 239.4 miles between the hours of 9:10 a.m. to 1:40 p.m.
1:40 p.m. is 13:40.
Thus, they traveled for
13 hours 40 minutes - 9 hours 10 minutes = 4 hours 30 minutes
that is hours.
Use formula:
where
D = distance
r = rate
t = time.
In your case,
D = 239.4 miles
t = 4.5 hours
X + 3 +2 > 15
Subtract 2 from both sides
X + 3 > 13
Subtract 3 from both sides ;)
X > 10
The percent of decrease from 20 to 16 is 20%
Answer:
Answer down below!
Step-by-step explanation:
−12x+14=−10x−8
Step 1: Add 10x to both sides.
−12x+14+10x=−10x−8+10x
−2x+14=−8
Step 2: Subtract 14 from both sides.
−2x+14−14=−8−14
−2x=−22
Step 3: Divide both sides by -2.
−2x
−2
=
−22
−2
x=11
