Answer:
t = Vp / 8
Step-by-step explanation:
Given:
V = 8t/p
Where,
V = volume
t = temperature
p = pressure
solve for temperature, t as a function of volume and pressure, v and p
V = 8t/p
Cross product
V*p = 8t
Vp = 8t
Divide both sides by 8
Vp / 8 = 8t / 8
Vp / 8 = t
Therefore,
t = Vp / 8
That is, temperature = product of volume and pressure divided by 8
Let X represent the cost of 1 pear and Y represent the cost of 1 peach.
Use the given information to set up a system of equations:
5X + 6Y = 11.20
3X = 2Y
Use the second equation to solve for Y:
3X = 2Y
Y = 1.5X
Plug the new found value for Y into the first, unused equation:
5X + 6(1.5X) = 11.20
Simplify:
5X + 9X = 11.20
or
14X = 11.20
Solve for X:
X = .8
Now that you have the value for X, you can plug it into either of the first two equations to solve for Y:
3X = 2Y
3(.8) = 2Y
2.4 = 2Y
Y = 1.2
Each pear is $0.80 and each peach is $1.20.
