Answer:
75
Step-by-step explanation:
assuming that all are children(answer will be adult ticket at the end)
124×5.20=644.8
872.5-644.8=227.7
8.50-5.20=3.30
227.7÷3=75.9=75 tickets(no decimal cause tickets are sold as a whole)
Answer and Explanation:
I'm assuming you mean the "Additive property of equality".
The additive property of equality states if the same value amount is added to both sides of an expression or equation, it will remain equal.
Similarly, the additive property of inequalities states if the same value amount is added to both sides of an inequality, it will remain true.
Answer:
The equation for a parabola with vertex at the origin and a directrix at x = 1/48 is 
.
Step-by-step explanation:
As directrix is a vertical line, the parabola must "horizontal" and increasing in the -x direction. Then, the standard equation for such geometric construction centered at (h, k) is:
Where:
, 
- Horizontal and vertical components of the location of vertex with respect to origin, dimensionless.
- Least distance of directrix with respect to vertex, dimensionless.
Since vertex is located at the origin and horizontal coordinate of the directrix, least distance of directrix is positive. That is:
Now, the equation for a parabola with vertex at the origin and a directrix at x = 1/48 is .
