Answer:

Step-by-step explanation:
AB = a
AP = 2PQ = 2QB
AB = AP + PQ + QB
= AP +
+ 
AB = 2AP
AP =
-----(1)
And we know QB = 
QB= AP/2 =
---------(2)
Now midpoint of AP =
×
= 
and midpoint of QB =
×
= 
distance between these midpoints =
- 
= 
Answer:
∠z is 79°
Step-by-step explanation:
Given, Customers pay $4 to enter the pumpkin patch.
And also given, customers pay $3 per pound for the pumpkins.
Given, $y be the total cost and there are x pounds of pumpkins.
The cost for pumpkin per pound = $3.
Therefore, the cost for x pound pumpkins = $(3x)
As the total cost includes the payment for entering the patch also,
So the total cost y = 3x + 4
We have got the required equation.
The equation to model the total cost is y = 3x+4.
