$75.14. formula as follows ($79.99 - (($79.99/100)x12)) + ((($79.99/100)x12)/100)*6.75)
Answer: 12 students = 3 adults. 24 students = 6 adults, 40 students = 10 adults
Step-by-step explanation: The ratio is 1 adult to every 4 students, so divide the number of students by 4
Answer:
(x+8)^2+y^2=16
Step-by-step explanation:
The equation for a circle in center-radius form is
(x-h)^2+(y-k)^2=r^2
where (h,k) is the center and r is the radius.
We are given the diameter is 8 so the radius is 8/2=4.
We are also given (h,k) is (-8,0).
The equation for the circle is
(x--8)^2+(y-0)^2=4^2
(x+8)^2+y^2=16
Answer:
x = 50
Step-by-step explanation:
Solve.
1. Solve for y.
6x + 3y = -12
2. Subtract 6x.
6x - 6x + 3y = -12 - 6x
3. Simplify.
3y = 6x + 12
4.Divide by 3.
3y/3 = (6x +12) / 3
5.Simplify.
y= 2x + 4
Answer: y= 2x + 4
