Answer: x = 109/48
Step-by-step explanation:
1. Simplify 4 x x/5 to 4x/5
1/4 + 4x/5 = 31 15
2. Subtract 1/4 from both sides
4x/5 = 31/15 - 1/4
3. Simplify 31/15 - 1/4 to 109/60
4x/5 = 109/60
4. Multiply 1both sides by 5
4x = 109/60 x 5
5. Simplify 109/60 x 5 to 545/60
4x = 545/60
6. Simplify 545/60 to 109/12
4x = 109/12
7. Divide both sides by 4
x = 109/12/4
8. Simplify 109/12/4 to 109/12 x 4
9. Simplify 12 x 4 to 48
x = 109/48
Hope this helps & happy halloween! :)

<h3>What is Unitary method?</h3>
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given: the group of friends had $280.
For parking= $19.50
Remaining will be,
=$(280-19.50)
= $ 260.5
Cost of ticket per person = $33.75
Thus, number of tickets they can buy
=260.5 / 33.75
=7.718 = 8 peoples
Hence, number of people who can go to the amusement park is 8.

Answer:
x = 20
Step-by-step explanation:
Perimeter = Sum of all sides
Perimeter = (x+4)+(4x)+10x-(10)
Where Perimeter = 294 in.
294 = 15x-6
15x = 294+6
15x = 300
Dividing both sides by 15
=> x = 20
