Answer:
38
Step-by-step explanation:
The simplest (almost trivial) solution is to add the two inequalities:
(x +3y) +(3x +2y) ≤ (13) +(25)
4x +5y ≤ 38
The maximum value of P is 38.
_____
Perhaps more conventionally, you can graph the equations, or solve them to find the point of intersection of their boundary lines. That point is (x, y) = (7, 2), which is the point in the doubly-shaded solution space that gives the maximum value of P (puts the objective function line farthest from the origin).
__
In the attached graph, we have been a little sloppy, not applying the constraints that x, y ≥ 0. For the purpose of finding the requested solution, that is of no consequence.
Answer:20
Step-by-step explanation:
because you are finding out the base so width times length
Answer:
The cost of the sofa is $216
Step-by-step explanation:
The sofa was sold at cost plus 25% profit
let the cost of the sofa be = x
therefore x + 25% of x = 270
x + .25x = 270
1.25x = 270
1.25x/1.25 = 270/1.25
x = $216
The answer to that problem is 4. 4*4*4*4=(4*4)*(4*4)=16*16=256. I hope this helped!
Answer:
3
Step-by-step explanation:
21 acres divided by 7 days equals to 3 days
Each day they do 3 acres
3 acres * 7 days = 21 acres in a week
