Answer:
![PQ = 42](https://tex.z-dn.net/?f=PQ%20%3D%2042)
Step-by-step explanation:
Given
![PT = 3x + 3](https://tex.z-dn.net/?f=PT%20%3D%203x%20%2B%203)
![TQ = 5x - 9](https://tex.z-dn.net/?f=TQ%20%3D%205x%20-%209)
Midpoint, T
Required
Determine PT
First, the value of x has to be calculated;
Since T is the midpoint, then:
![PT = TQ](https://tex.z-dn.net/?f=PT%20%3D%20TQ)
This implies
![3x + 3 = 5x - 9](https://tex.z-dn.net/?f=3x%20%2B%203%20%3D%205x%20-%209)
Solve for x
![3x - 5x = -3 - 9](https://tex.z-dn.net/?f=3x%20-%205x%20%3D%20-3%20-%209)
![-2x = -12](https://tex.z-dn.net/?f=-2x%20%3D%20-12)
![x = -12/-2](https://tex.z-dn.net/?f=x%20%3D%20-12%2F-2)
![x = 6](https://tex.z-dn.net/?f=x%20%3D%206)
Length PQ can then be calculated using:
![PQ = PT + TQ](https://tex.z-dn.net/?f=PQ%20%3D%20PT%20%2B%20TQ)
![PQ = 3x +3 + 5x -9](https://tex.z-dn.net/?f=PQ%20%3D%203x%20%2B3%20%2B%205x%20-9)
Collect Like Terms
![PQ = 3x+ 5x +3 -9](https://tex.z-dn.net/?f=PQ%20%3D%203x%2B%205x%20%2B3%20%20-9)
![PQ = 8x -6](https://tex.z-dn.net/?f=PQ%20%3D%208x%20-6)
Substitute 6 for x
![PQ = 8 * 6 - 6](https://tex.z-dn.net/?f=PQ%20%3D%208%20%2A%206%20-%206)
![PQ = 48 - 6](https://tex.z-dn.net/?f=PQ%20%3D%2048%20-%206)
![PQ = 42](https://tex.z-dn.net/?f=PQ%20%3D%2042)
-1 over 1 you divide by 22
Answer: 389
Step-by-step explanation: well if there is lollipops for $2.50 each and they sold thrice as many lollipops then they have sold 7.5 of the lollipops and if you sell thrice of the cookies then that will be 31.5 and if you add 7.5 and 31.5 that will be 39 so the real answer is 389.
