Answer: 1 hour 15min
Step-by-step explanation:
When Paul passes the gas station Mary si already 12.5 miles away
X=v t = 50mph 0.25h = 12.5 miles. (15min equals a quarter hour)
From that moment to the meeting point we’ll have only one t (time) and one x (final point) for both cars
For Mary we have
X= Xo + v t= 12.5 miles + 50mph t
For Paul we have
X=v t = 60mph t
As x si the same in both equations
60mph t = 12.5 miles + 50mph t
(60mph - 50mph) t = 12.5miles
10mph t = 12.5miles
t = 12.5miles/10mph
t = 1,25 h
Answer:
z=-11
Step-by-step explanation:
subtract the 17 to get it on the same side as the 6 so, 6-17=z, then simplify so -11=z
7526.44 because you look at the thousanth place (the 2) and since it is less than 5 you round down
Answer:
What are we trying to slove?
Step-by-step explanation:
Answer:
Length = 14, Width = 7
Step-by-step explanation:
Step 1:
Length + Length + Width + Width = Perimeter
Step 2:
2w + 2w + w + w = 42
Step 3:
6w = 42
Step 4:
w = 7
Step 5:
7 × 2 = 14
i hope this helps you. :)
