Answer:
14, 21, and 63
Step-by-step explanation:
we can set the three unknown numbers as x, y, and z
so
x + y + z =98
now we are given that the first (x) is seven less than the second (y)
x = y - 7
the third number (z) is three times the second (y)
z = 3y
since we have an equation for z and x in terms of y, we can plug it into the first equation and solve for y.
(y-7) + y + (3y) =98
y - 7 + y + 3y =98
y + y + 3y =105
5y = 105
y=21
now that we know y, we can plug its value into either the second or the third equation to find x or z (I chose to find z first)
z = 3y
z = 3(21)
z = 63
now we can plug in y to find x
x = y - 7
x = 21 - 7
x = 14
so the three numbers should be 14, 21, and 63
Using x as the number of adult tickets sold
If 3x as many student tickets were sold as adults
--> the number of student tickets is 3x
If the total tickets is 572 and made up of 3x and x
This equation represents the relation ship
Total = 572
number of adult tickets + number of student tickets = 572
x + 3x = 572
When solving for x, we will find the number of adult tickets
x+3x =572
4x=572
x= 572/4
x= 143
143 adult tickets were sold
Point-Slope Equation: y - y₁ = m(x - x₁) ; where (x₁, y₁) is the point and m is the slope
(x₁, y₁) = (4, 1700) and m = 200
y - 1700 = 200(x - 4)

Answer:
I wanna say b
Step-by-step explanation:
I'm gonna say b because u would think since they've paid $13, and it sells for $22, u would add that on the price, which in my opinion would be x + 13 = 22
