Answer:
it's 4.5
Step-by-step explanation:
you have to find the difference between each number and the mean. then you find the mean of that sum
The Given equation is , 3 x + x = 440,
Let speed of train A is x Km/hour and Speed of train B which is a Bullet train which starts from same station but from different platform is 3 times the speed of train A.
And Sum of their Velocities is i.e Velocity of train A and Velocity of train B is 440 Km/hour.
I think the answer is
x < (2b -8) / 3
or
x < 2b/3 - 8/3
Answer:coefficient of x term is 8
Step-by-step explanation:I(2x-5)(x2-3x2+4)
(2x-5)(-2x2+4)
-4x3+8x+10x2-20
coefficient of x is 8
