Answer:

15 classes

Step-by-step explanation:

Let

x -----> the number of class

y ----> the total amount in charges

we know that

The total charge is equal to the number of class multiplied by the additional fee plus the membership fee (only members)

so

<em>Members</em>

y=3x+75 -----> equation A

<em>Non Members</em>

y=8x -----> equation B

Equate equation A and equation B

8x=3x+75

Solve for x

8x-3x=75

5x=75

x=15

How to solve this equation algebraically: Y=2x+1<br> 3x+4y=26
AURORKA [14]
You can substitute what y is into the second equation, so:
3x + 4(2x + 1) = 26
3x + 8x + 4 = 26
11x + 4 = 26
- 4
11x = 22
÷ 11
x = 2

y = (2 × 2) + 1
y = 5 + 1
y = 5

So you get x as 2 and y as 5, I hope this helps!

Artist 52 [7]

Answer:

Step-by-step explanation:

You have a circle with radius r = 3 ft and a 3-by-12 rectangle.

Area of circle = πr² = 9π ft²

Area of rectangle = 3 × 12 = 36 ft²

Total area = 36 + 9π ≈ 64.3 ft²

Perimeter of circle = 2πr = 6π ft

Perimeter of rectangular projections = 18 ft

Total perimeter = 6π +18 ≈ 36.8 ft
