Answer:
(First step for obtaining a common denominator for the two fraction)

Step-by-step explanation:

where,
a is acceleration of an object.(Need to calculate)





Now we will simplify above expression for a
First we make common denominator.
Common denominator is 7. So, we make both denominator 7. We multiply by 7 at top and bottom with 3. We get
(First step for obtaining a common denominator for the two fraction)
Now we combine the numerator


we have

This is a mixed number
we know that
A mixed number is a combination of a whole number and a fraction.
So
is equal to

where
is the whole number
is the fraction

therefore
the answer is

The correct answer is C. 2y = 22
5(x-3)-x =
Multiply Everything In The Parentheses By 5
5x-15-x
