Answer:
6
Step-by-step explanation:
When doing this let's start by doing the math in the parenthesis.
(6 - 4) ∙ (3^2) ÷ (2 + 1)
(2) * (9) / (3)
This next step can be solved using PEMDAS and when there is a multiplication and division possibility you do the one that comes first in the equation so 2 * 9 in our case.
(2) * (9) / (3)
18 / 3
Lastly, we have a division equation which is obvious to solve.
18 / 3

Hope this helps :)
Let
x: pay of parasailing per hour
y: pay of horseback riding per hour:
We have the following system of equations:
2x + 5y = 205
3x + 3y = 240
Solving the system we have
6x + 15y = 615
6x + 6y = 480
Subtracting both equations:
9y = 135
y = $ 15 / h
Then,
x = (1/2) * (- 5y + 205)
x = (1/2) * (- 5 * (15) +205)
x = 65 $ / h
you want to go parasailing for 1 hour and horseback riding gor 2 hours
x + 2y
65 + 2 * (15) = 95 $
answer
you expect to pay $ 95 for 1 hour and horseback riding gor 2 hours
Y = kx, so y/x is constant
you want y such that
y/12 = -2/-8
1.50 that should be it and i dont know how to show my work on a computer SORRY.
