Answer:
B) x = 2, y = 1
Step-by-step explanation:
Add the two equations to eliminate the x-variable.
(x +3y) +(-x +6y) = (5) +(4)
9y = 9 . . . . . . .simplify
y = 1 . . . . . . . . divide by 9
You can substitute this value into either equation to find x.
x + 3(1) = 5
x = 2 . . . . . . . . subtract 3
The solution is (x, y) = (2, 1).
Let x ft be the lenght of the fence and y ft be the width of the fence.
1. The length of the habitat should be at least 80 feet, then

2. The perimeter of the habitat should be no more than 300 feet. The perimeter of the fenceis 2x+2y ft, then

3. The system of inequalities that represent the model is

The graph of these inequalities is attached.
Two possible solutions are
- x=100 ft, y=20 ft (100≥80 and 2·100+2·20=240≤300);
- x=110 ft, y=30 ft (110≥80 and 2·110+2·30=280≤300).
Answer:
V = 27.4 in^2
Step-by-step explanation:
Converting to mixed numbers with fractions in decimal format makes this problem easier. 2 1/2 inches is the same as 2.5 inches; 5 1/2 inches is 5.5 inches.
The volume formula is V = L*W*H.
Here, V = (5.5 in)(2.5 in)(2 in), or 27.4 in^2
Answer:
7 x + 3 +24
Step-by-step explanation:
The answer is 7 x + 3 =24 because its a problem solving
