Answer:
Step-by-step explanation:
"Five times a number" is '5x'.
"Decreased by nine is" '-9'.
"Is equal to" is '='.
"Twice the number" is '2x'.
"Increased by 23" is '+ 23'.
Put them together: 5x-9=2x+23
5x - 9 = 2x + 23 should be the correct answer.
Answer:
The distance covered is 113.75 m
Step-by-step explanation:
As per the question:
The initial velocity of the train, v = 20 m/s
The final velocity of the train, v' = 6 m/s
Uniform deceleration, a = 1.6
Or uniform acceleration, a = - 1.6
<em>Here, the body decelerates, i.e., slows down at a uniform rate thus we take acceleration with negative sign.</em>
Now, to find the distance covered, s:
Using the eqn of Kinemetics:
Simplify
5 - 2i + 3 + 4i - (-6 + 2i)
Simplify brackets
5 - 2i + 3 + 4i + 6 - 2i
Collect like terms
(5 + 3 + 6) + (-2i + 4i - 2i)
Simplify
<u>= 14</u>
