Length of train : 100
length of bridge : 400
distance covered by the train to cross the bridge : (100 + 400) = 500
time taken by the train to cross : 30

speed = distance / time
speed = 500/30
speed = 16.67 meters per second <===

Slove for x: x+1/3=1/4
lana [24]
Hey!


To solve this problem, we must subtract one over three from both sides of the equation. This will give us x on its own.

<em>Original Equation :</em>
x + \frac{1}{3} = \frac{1}{4}

<em>New Equation {Added Subtract \frac{1}{3} to Both Sides} :</em>
x + \frac{1}{3} - \frac{1}{3} = \frac{1}{4} - \frac{1}{3}

<em>Solution {New Equation Solved} :</em>
x=- \frac{1}{12}

<em>So, this means that in the equation provided</em>,  x=- \frac{1}{12}.

Hope this helps!

Find the quotient of `(2i(4+5i)(4-5i))/(4+i)`, and express it in the simplest form.
DIA [1.3K]

Answer:

(328i + 82)  /  17

Step-by-step explanation:

`(2i(4+5i)(4-5i))/(4+i)

= (2i(16 - 25i^2)) / (4 + i)

= (2i( 16 + 25) )) / (4 + 1)        [Note:- i^2 = -1]

=  82i / (4 + i)

= 82i(4 - i) / (4 + i)(4 - 1)

= 328i  + 82 /   (16 - i^2)

= (328i + 82)  /  17
