Answer:
A car's velocity changes from 25 m/s to 20 m/s in 5 seconds.
Step-by-step explanation:
By definition, Acceleration is the rate of change of Velocity of an object.
I.e it is the( final velocity minus initial velocity ) ÷ by the time it took for the velocity to change.
If we observe the choices only one choice gives us all 3 components (final velocity, initial velocity, time taken for velocity to change), which is :
A car's velocity changes from 25 m/s to 20 m/s in 5 seconds.
Sara got 88, 90, 75, 78, 100, 54, 90, 100, 45, and 60 on her English tests. Lee got 77, 67, 99, 79, 100, 65, 79, 89, 58, and 67

The mean is the average, so I added up all the numbers and divided that by the number of tests:
Sara's mean: 78
Lee's mean: 78
Plug in the to X value in

Answer:
The coefficient of
is 
Step-by-step explanation:
The two expressions are
and
.
The sum of the two expressions is

When we group like terms the expression will be,

When we simplify the expression will now be

The coefficient of
is the constant behind
in the expression.
The coefficient of
is therefore
.
