So, we have:
Answer:
25%
Step-by-step explanation:
The café served 15 decaffeinated coffee and the percentage of 15 out of 60 is 25.
Answer:
The Solution of the equation is
x= 5 ±
Step-by-step explanation:
We are supposed to find the solution of the equation by completing square method
our given equation is
2x² + 20x + 10 = 0
Dividing whole equation by 2
we will get
x² + 10 x + 5 = 0
Now we will write the middle term in factor form to see what we will be needing to make it perfect square
it would be written as
x² + 2(5) x + 5 = 0
Now adding 20 on both sides we get
x² + 2(5) x + 5 + 20 = 20
x² + 2(5) x + 25 = 20
(x)² + 2(5) x +(5)² = 20
Now we have the form of a²+2(a)(b) + b²
And also we know that
a²+2(a)(b) + b² = (a+b)²
So our equation becomes
(x+5)² = 20
Taking square root of both sides it becomes
square cuts out with square root so
it becomes
x+5 = ±
We know that
So it becomes
x+5 =±
Subtracting 5 from both sides
it becomes
x= 5 ±
So
The Solution of the equation is
x= 5 ±
Multiple the all fraction and the x marks relating to how many there are.
Then Add then all up. Finally, divide by how many x marks there is.
2(1/8)+4(1/4)+2(3/8)+2(1/2) = 3
------> 3 / number of x, 3 / 10 or.3
