16. 27/20 = k/2
Switch sides. (Optional)
k/2 = 27/20
Multiply them by 10.
k/2 × 10 = 27/20 × 10
Simplify.
5k = 27/2
Divide both sides by 5.
5k÷5 = 27/2÷5
Simplify.
k= 27/10
Answer:
31 is the answer of this question
20% Because $18.00 - $14.40 = $3.60
3.6/18 = 0.2 ---> 20%
Answer:
x = 5
Step-by-step explanation:
x + 5 =
{Midpoint theorem}
2(x+ 5) = x² - x
2x + 10 = x² - x
x² - x - 2x - 10 = 0
x² - 3x - 10 = 0
x² - 5x + 2x - (5*2) = 0
x(x - 5) + 2(x - 5) = 0
(x -5)(x + 2) = 0
{x + 2 is ignored because measurement could not be in negative value}
x - 5 = 0
x = 5
