You have to add all three concerts 953+1100+1100 =3,163
And the answer you have divided by 3
The average of people at the concerts were 1,054
So 65 dollars was what she paid
each camera INCLUDED a 60% mark UP so
she sold each at a 60% markup
65 dollars=100% of origonal camers
she sold them for 100+60=160% of origonal price
65 dollars=100%
percent means parts out of 100 so
160%=160/100=1.6
find 160% of 65
'of' means multiply so
1.6 times 65=104
she sold each camera at $104
The axis of symmetry of a parabola in the form
is a vertical line
where k is the x coordinate of the vertex of the parabola.
The x coordinate of the vertex of the parabola is given by
which in your case is
So, the axis of symmetry is the line x=12.
That is:
2x^2+5(9x-3)×2
2x^2+(45x-15)×2
2x^2+90x-30
2(x^2+45x-15)
Answer:
20
Step-by-step explanation:
Using the rule of radicals
× ⇔
Simplify
= = × = 2
Thus
6 + 8
= 6(2 ) + 8
= 12 + 8
= 20
