1)
b: 3.75 since it is half of the segment that measures 7.5, this is proven because the line in the middle is a bisector of the top and bottom line indication that both half measure the same; 3.75
2) 15 not sure why
A - 1766! I hope this helps
X=12
This is because you subtract 6 from both sides to get the x isolated.
So x=18-6
x=12 :)
Good to see you here. Now back to the train.
Kaduna, K Lagos, L
Train leaves at 64 km/h
One hour late second train leaves Lagos at 96 km/h.
At the point they meet, if first train has been travelling for "x" hours. Second train has been travelling for (x-1) hour.
At the point the meet, the total distance travelled is equal to 624 km.
Therefore:
64(x) + 96(x-1) = 624
64x + 96x - 96 = 624
160x = 624+96
160x = 720 , x = 720/160 = 4.5
So when they meet, the first train which left Kaduna has travelled= 64x = 64*4.5= 288km from Kaduna.
So it is (624-288) km from Lagos. = 336 Km from Lagos.
Second train which left Lagos has travelled = 96(x-1) = 96(4.5-1) = 336km.
The second train is also 336 km away from Lagos.
Cheers.
