The three angle bisectors of ΔABC meet at P. Drag the vertices around to form different triangles, and then make a conjecture. W

To solve this problem, you'll need to create two equations:
x + y = 155 (total packages)
3x + 8y = 815 (total weight)
Next, multiply the first equation by 3: 3x + 3y = 465.
Then, subtract the first equation from the second to find that 5y = 350, which means y = 70. Thus, there are 70 packages that weigh 8 pounds. 

To determine the time interval δt, we must subtract the starting time from the ending time. In this scenario, the first value in the coordinates signifies time:

δt=50 - 0
δt= 50s

The time interval is 50s.

Answer:

The attached figure illustrates the graph.

Step-by-step explanation:

Let

x represents the count of open acres

y depicts the total developed acres

It is established that

corresponds to inequality A

corresponds to inequality B

Keep in mind that

if the open acres, x, is limited to a maximum of 1, then it follows that x must adhere to ≤ 1

The system of equations can be solved by graphing

The solution is found in the shaded area (Note Negative acreage counts are not permissible)

The attached figure serves as a visual representation.

The equivalent ratio is 3/4.
