so the basic formula for this d = rt
where d is the distance , r is the speed and t
is time
3800 – 120t = 520 + 40t ( this is the altitude
of each plane are equal)
Solve for t
T = 20.5 min time it takes for the planes to be
at the same altitude
3800 – 120(20.5) = 1340 ft

Answer:
3 because 3 x 2 + 3 x 8 = 30 and 3(2+8)=30
Answer:
75?
Step-by-step explanation:
is there more to the question?
Subtract 9/4 from both sides
3/4x=6 3/4
Multiply them by 4/3
X=9
Answer:
x=8
Step-by-step explanation:
2x+9=3x+1
-3 -3
-9 -9
-1x=-8
divide both side by -1.
x=8
