Let x = Pacific Paradise
You can set up the equation like this:
x + (3x - 25) + (x + 18) = 928
(Combine like-terms)
5x - 7 = 928
(Add 7 to both sides)
5x = 935
(divide by 5 to both sides)
x = 187 (# of deluxe staterooms Pacific Paradise)
Next to find the # of deluxe staterooms of the other cruise ships create two equations
Let y = Carribean Paradise
x + 18 = y
(plug in the value of x which is 187)
187 + 18 = y
(combine like-terms)
205 = y (# of deluxe staterooms Carribean Paradise)
Let z = Mediterranean Paradise
3x - 25 = z
(plug in the value of x which is 187)
3(187) - 25 = z
(follow PEMDAS to simplify and combine like-terms)
536 = z (# of deluxe staterooms Mediterranean Paradise)
Finally check your answer by adding up all of your answers to make sure it equals 928
536 + 205 + 187 = ? (928!)
Answer:
x=3
Step-by-step explanation:
plug in -2 for y. then you can find the x value, which is 3
Answer:
The volume in such a package is 10,415.41 in³
Step-by-step explanation:
Consider the provided information.
A parcel delivery service will deliver a package only if the length plus the girth (distance around, taken perpendicular to the length) does not exceed 104 inches.
Let the dimension are x by x by y.
Where x is the variable for the square base package and y is the variable for length.
Thus l=x, b=x and h=y
Then the volume of the box is: 
(∵V=lbh)
The maximum combined length and girth is 104.
Therefore, 
Substitute the value of y in volume of the box.
Substitute V'(x)=0.
Now apply second derivative test.
(Min)
(Max)
If x=52/3 then 
Substitute x = 52/3 and y = 104/3 in
Hence, the volume in such a package is 10,415.41 in³
Answer:
Step-by-step explanation:
hello :
7x-6 = 3x+14
7x-3x =14+6
4x=20
x=20/4
