<span>t in (-oo:+oo)
(3*t)/2+7 = 4*t-3 // - 4*t-3
(3*t)/2-(4*t)+3+7 = 0
(3*t)/2-4*t+3+7 = 0
10-5/2*t = 0 // - 10
-5/2*t = -10 // : -5/2
t = -10/(-5/2)
t = 4
t = 4 is the answer
hope it helps~

Answer:
9/10
Step-by-step explanation:
Since there is only one marble per number and there is only one marble for the number 8 you would take just subtract 10-1 which would give you 9.
Answer:
S = v1 t1 = 7 t1 traveling downstream
S = v2 t2 = 5 t2 traveling upstream
7 t1 = 5 t2
7 (6 - t2) = 5 t2 since t1 + t2 = 6
42 - 7 t2 = 5 t2
t2 = 42 / 12 = 3.5 hrs so t1 = 2.5 hrs
S = 7 t1 = 7 * 2.5 = 17.5 mi
Also, S = 5 t2 = 5 * 3.5 = 17.5 mi
