Solution: Let
be the number of adult ticket's.
The number of child ticket 
We are given, that an adult ticket cost's $10 and child ticket costs $6. Also the church luncheon made $842.
Therefore,





Therefore, the number of adult ticket's sold = 35
And the number of child ticket's sold = 2 x 35 + 12 = 70 + 12 = 82

Its the top one b
I think that the only way to find the answer is to evaluate points into the different equations
Answer:
Options (1) and (2)
Step-by-step explanation:
In 3-dimensional geometry,
Skew lines are lines which do not intersect and are not parallel.
From the given triangular prism,
Option (1). RS and TU
Sides RS and TU are neither parallel nor intersect each other.
Therefore, these lines are skew lines.
Option (2).QR and SV
Since QR and SV neither intersect nor parallel,
These lines are the skew lines.
Option (3) RS and RU
Since RS and RU intersect at R therefore, they are not the skew lines.
Option (4).RS and UV
Since RS and UV are the parallel lines therefore, they are not the skew lines .
Answer:
A: 7.5
Step-by-step explanation:
If the length is 5 inches longer than the width, we must multiply the width by 4 and add ten to figure out the perimeter. 7.5 x 4 = 30. 30 + 10 = 40.
