Answer:
x = 29/8c
Step-by-step explanation:
2/3(cx+1/2) - 1/4+ 1/4 = 5/2+1/4
2/3(cx+1/2) = 11/4
1/3(cx+1/2) = 11/4 / 2
cx/3 + 1/2/3 = 11/4/2
cx/3 + 1/2*3 = 11/4/2
cx/3 + 1/6 = 11/4/2
cx/3 + 1/6 = 11/4*2
cx/3 + 1/6 = 11/8
cx/3 = 11/8 - 1/6
cx/3 = 29/24
cx = 29/24 * 3
x = 29/8 / c
x = 29/8c
-- 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.
Answer:
31*
Step-by-step explanation:
right triangle means 90* so 90*-59* = 31*
Answer:
21.2 or 15 sqrt of 2 (PETHAGOREOM theorem)
Step-by-step explanation:
a^2+b^2=c^2
20^2+5^2=C^2
400+25=C^2
450=C^2
sqrt 450=
15 sqrt of 2 or 21.2
