Answer: The missing length is 40 m.
Step-by-step explanation:
30^2 + b^2 = 50^2
900 + b^2 = 2500
-900 -900
b^2 = 1600
b= 40
-- The trains start moving at the same time.
-- The space between them is initially 252.5 miles.
-- They reduce the distance between them at the rate of (124.7+253.5)=378.2mph.
-- It will take them (252.5 / 378.2) = 0.6676 hour to meet.
That's 40min 3.49sec .
-- After tooting and puffing toward each other for 8 minutes, they still have <em>32min 3.49sec</em> to go before they meet each other. We're all hoping that they're on different tracks.
Use the distributive property to multiply 3 by x−4.
Subtract 5x on both sides.
Combine 3x and −5x to get −2x.
Add 12 to both sides.
Divide both sides by −2. Since −2 is < 0, the inequality direction is changed.
So in the <u>inequality 3(x-4)>5x +2</u>, the value of x is -7.
