Given situation: There were 548 films released in 2011. Rated PG were approximately 8.75% of the released movie.
Question: Find how many PG movies were released in 2011. PG means Parental guidance.
Solution,
=> 8.75% = 8.75 / 100 = 0.0875
=> Now, let’s multiply this decimal number to the total number of films released.
=> 548 * 0.0875
=> 47.95. Round off to 50.
Thus, there were approximately 50 films released that were Rated PG.
Step-by-step explanation:
Divide by any number except 0 means the same as multiply by its inverse.
The inverse of
is 
Therefore

Used the commutative property of multiplication: a × b = b × a

D
given the 2 equations
x + 2y = - 8 → (1)
- 4x + y = 5 → (2)
multiply (1) by 4
4x + 8y = - 32 → (3)
add (2) and (3) term by term to eliminate term in x
9y = - 27 ( divide both sides by 9 )
y = - 3
substitute y = - 3 in either (1) or (2) and solve for x
(1) : x - 6 = - 8 ( add 6 to both sides )
x = - 2
solution is (- 2, - 3 ) → D
