Answer:
8
Step-by-step explanation:
Let the number of hours = X
Multiply the speed of each train by the number of hours (x) and add them together to equal the total miles:
75x + 95x = 238
Simplify:
170x = 238
Divide both sides by 170:
x = 238/170
x = 1.4 hours.
Check:
75 x 1.4 = 105 miles
95 x 1.4 = 133 miles
105 + 133 = 238 miles
It will take 1.4 hours ( 1 hour and 24 minutes).
Answer:
70
Step-by-step explanation: Lets say x is the integer
5,600/x=80 is the same as
5,600÷x=80.
You should then rewrite it as 5,600÷80=x
Now simplify.
x=70
-mn^2-5m^2/(5m-2)(m+4n)
if I did it correctly
The formula is (degree)x(pi÷180)
36 x pi ÷ 180
0.63 rad
