Answer:
x = 
Step-by-step explanation:
3(2x - 3) + 4(2 - x) = 0 ← distribute parenthesis
6x - 9 + 8 - 4x = 0 , that is
2x - 1 = 0 ( add 1 to both sides )
2x = 1 ( divide both sides by 2 )
x = 
Answer:
Yes
Step-by-step explanation:
It is a random sample of the green balls in a bag because it never states that he is doing it someone.
In order to find the second endpoint or a line segment given the first and the midpoint, you need to realize that the midpoint is an average of the two endpoints. Given that fact, we can derive this formula looking at x values of points A and B with midpoint M. Remember this is only looking at the x values.
(A + B)/2 = M
So if we are looking for A, we can solve for A and use this modified formula.
(A + B)/2 = M
A + B = 2M
A = 2M - B
Now we can do this with the y values of these points as well. We then have the coordinates of both parts of A.
136×25%=136×25/100= 3 400/100=34
so the markeup value is
136+34= 170
170×17%=170×17/100=2 890/100=28.9
170-28.9=141.1
Selling price=136+170=306
Density is calculated by mass divided by volume.
This would be 60/24 (60 grams mass divided by 24 cm^3 volume)
60/24 = 2.5
This means the answer is B. 2.5 g/cm^3
