SOLUTION
At the same time t,
Train 1 would have covered a distance of 80t, since distance = average speed x time.
Train 2 would have covered a distance of 70t.
Now both added should give 210 miles
That is 80t + 70t = 210
150t = 210
t = 210/150
t = 1.4 hours
5. area 0.75*2*0.75*2=2.25 m²
scale 1 in.=2 m so
The equation has no solution because:
5(n+10)=5n+10n
5n+10n=5n+10n
I subtract 5n from both sides
10n=10n
Only one side is supposed to have the variable which is n, so the equation has no solution.
The train will have been traveling for 4 hours
train A=45,90,135, 180
train B=0,60,120,180
Answer:
C
Step-by-step explanation:
Since "P" is -4, add POSITIVE 6.5 to it. It makes 2.5
hope it helps :D
