The Buchanan Town Carnival charges $5 to enter and $2 for each ride. Write an expression to represent how much it would cost to
go to the carnival and ride r rides. Then, figure out how many rides you could ride if you have $17.00.
1 answer:
Answer:
6 rides
Step-by-step explanation:
Let "y" represent the total cost...
Equation: y = 2r + 5
To figure out how many rides you could ride if you have $17.00, set y equal to 17:
17 = 2r + 5
12 = 2r
r = 6

4(2)+2(2)=12
B. four times the value of y = the value of y+9
X*y=72
x = 5y-2
x=72/y
72/y=5y-2
72=5y^2-2y
5y^2 -2y - 72 = 0
(5y+18)(y-4)=0
y = -18/5 discard
or y = 4
4x=72
x=18
(18,4)
