5 = 15/3
3 1/3 = 10/3
15/3 - 10/3 = 5/3
so 5-3 1/3 is either 5/3 or 1 2/3.
Answer:
28 action movies
Step-by-step explanation:
- Set up a proportion:
- Cross multiply, then divide: 35 × 4 = 140, 140 ÷ 5 = 28
- So, if you have 35 comedy movies, you would have 28 action movies.
I hope this helps!

Step-by-step explanation:
A quadratic equation is a polynomial of degree two. A quadratic equation is in the form:
ax² + bx + c = 0; where a, b, c are constants.
Quadratic equation can be solved using different methods, such as completing the square method, quadratic formula.
Solving the equation 2x² - 10x - 20 = 8 using completing the square:
2x² - 10x - 20 = 8
2x² - 10x = 28
Divide through by 2, to make the coefficient of x² to be 1:
x² - 5x = 14
Add to both sides, the square of half of the coefficient of x [i.e. (-5/2)² = 6.25]
x² - 5x + 6.25 = 14 + 6.25
(x - 2.5)² = 20.25
taking square root of both sides:
x - 2.5 = √20.25
x - 2.5 = ±4.5
x = 2.5 ± 4.5
x = 2.5 + 4.5; or x = 2.5 - 4.5
x = 7 or x = -2
