Let the time = x
Distance = Speed x time
One train is 75x, the other train 85x
Add together to equal total distance:
75x + 85x = 384
Simplify:
160x = 384
Divide both sides by 160:
x = 384 / 160
x = 2.4 hours
Answer:
(f+g)(x)=2x+1+5 - x
(f+g)(x)=x + 6
(f - g)(x)= 2x + 1 - (5- x )
(f - g)(x)= 3x - 4
Answer:
63
Step-by-step explanation:
40/100 + 50/100 = 90/100
il lui reste 10/100 ou 21 $
10 % = 21 $
100 % = 210 $
I believe the answer is 28.27, or 28.3
