Well the way you would do it is you would add all of them up and then divide them by how much there is so the numbers added up give you 310 divided by 5 is 62 hop this helps!!!
Step-by-step explanation:
Given that,
A quadratic equation,
2x(x + 1.5) = -1
We need to solve the quadratic equation. Firstly we need to simplify the above equation to form it as
.
So,

Here, a = 2, b = 3 and c = 1
The roots of the given equation can be given by :

Putting all the values we get :

So, the roots of the given equation is -1/2 and -1.
Answer:
X=6.1
Step-by-step explanation:
x-5=0.1(x+5)
x-5=0.1x+0.5 (distribute 0.1)
x=0.1x+0.5+5 (add 5 to each side)
x-0.1x=5.5 (subtract 0.1x from each side)
0.9x=5.5 (combine like terms)
x=5.5/0.9 (divide by 0.9 on both sides)
x=6.1 (simplify)
Answer:
Option (B) 5.1 units
Step-by-step explanation:
Since the radius of the circle is half of its diameter and given the diameter of the circle is 10.2 units then the radius would be 
Thus the answer.
