Answer:
The cost of one adult ticket is $8 and cost of one student ticket is $4.
Step-by-step explanation:
Let,
x be the price of one adult ticket
y be the price of one student ticket
According to given statement;
12x+7y=124 Eqn 1
x+3y=20 Eqn 2
Multiplying Eqn 2 by 12
12(x+3y=20)
12x+36y=240 Eqn 3
Subtracting Eqn 1 from Eqn 3
(12x+36y)-(12x+7y)=240-124
12x+36y-12x-7y=116
29y=116
Dividing both sides by 29
Putting y=4 in Eqn 2
x+3(4)=20
x+12=20
x=20-12
x=8
Hence,
The cost of one adult ticket is $8 and cost of one student ticket is $4.

Answer:
8/3 or 2(2/3) Textbooks to storybooks
Step-by-step explanation:
Textbooks: (8 books)*(12 rupees/book) = 96 rupees
Storybooks: (4 books)*(9 rupees/book) = 36 rupees
Total is 132 rupees
Ratio: Textbook/Storybook = 96/36
96/36 = 8/3 or 2(2/3) Textbooks to storybooks

Answer:
the value of x is 25 degrees
Step-by-step explanation:
Here, we want to get the value of x
we use an important triangle angular principle here
And the principle is that when we add two opposite interior angles, we get the value of the exterior angle on the third side
Thus, mathematically;
x + 75 = 4x
4x-x = 75
3x = 75
x = 75/3
x = 25 degrees
