Answer:
Step-by-step explanation:
It is convenient to use the variables "a" and "c" for the number of adult tickets and child tickets, respectively. Two equations using these two variables can be written based on the given information:
7a +5c = 350 . . . . total revenue from ticket sales
a - c = 10 . . . . . . . . 10 more adult tickets were sold

Comment on the question
The solution to these equations is a=33 1/3; c=23 1/3. There is no integer solution. In real-world terms, the given relations cannot exist.
The combinations of sizes allow him to empty the bathtub in exactly four trips is a 5-liter bucket with the 3-liter bucket twice, a 3-liter bucket and the 4-liter bucket.
The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Paul's bathtub is clogged. He has to empty 30 liters of water by hand.
Paul has a 3-liter, a 4-liter, and a 5-liter bucket.
If Paul carries two buckets each trip, we need to find the combinations of sizes that allow him to empty the bathtub in exactly four trips.
5 and 3 = 8 liters ,
5 and 4 = 9 liters,
3 and 4 = 7 liters.
8 + 7 + 8 + 7 = 30 liters,
So,
He can take the 5-liter bucket with the 3-liter bucket twice, and then he can use the 3-liter bucket and the 4-liter bucket twice.

Answer:
55°
Step-by-step explanation:
Draw the diagram according to the given data (see attached diagram).
In this diagram,
Note that ∠GCH=35°
Angles GCH and CDI are corresponding angles. By corresponding angles postulate, angles GCH and CDI are congruent.
Angles CDI and BDE are vertical angles, so angles CDI and BDE are congruent as vertical angles.
Consider right triangle BDE. The sum of two acute angles of the right triangle is 90°, so
m∠BED=90°-m∠BDE
m∠BED=90°-35°=55°
