Answer:
2/3
Step-by-step explanation:
if we divide 10 by 3 then we get 3.3 repeating so just use the fraction 1/3. if you use 2 of the divided lengths then you get 2/3
Answer:
x = 2,−6
Step-by-step explanation:
Move all terms to the left side and set equal to zero. Then set each factor equal to zero
Step 1-Distributive Property
8c-72=12c-2-4c
Step 2-Combine Like Terms
8c-72=8c-2
Step 3-Divide both 8c's by 8
-72=-2 -72 does NOT equal -2 so this equation has no solution...Hope this helps have a great Day!!!
Answer: the rate of the passenger train is 100 mph.
Step-by-step explanation:
Let x represent the rate of the passenger train.
The rate of the freight train was 10 miles per hour slower than the rate of the passenger train. It means that the rate of the freight train is (x - 10) mph
The passenger train traveled 100 miles. It means that the time it took travel 100 miles is
100/x
In the same amount of time, it took a freight train to travel 90 miles. It means that the time it took travel 90 miles is
90/(x - 10)
Since the time is the same, then
100/x = 90/(x - 10)
Cross multiplying, it becomes
100(x - 10) = 90x
100x - 1000 = 90x
100x - 90x = 1000
10x = 1000
x = 100 mph
