Answer:
The price of each hamburger is $5 and the price of each drink is $3.
Step-by-step explanation:
- x --> the price of each hamburger
- y --> the price of each drink
- 8x+4y=52
- 5x+7y=46
- Solve system of equations
- The intersection is (3,5)
Let x represent the width of the garden(s). Then the length of the second garden is (3x+3). The area is the product of length and width,
90 = x(3x+3)
30 = x(x+1)
At this point, you can recognize that 5 and 6 are factors of 30 that will satisfy this equation, or you can solve the quadratic
x² +x -30 = 0
(x +6)(x -5) = 0
x = 5 . . . . . . . the negative solution does not apply
The width of the garden is 5 m.
A because it has to be less than or equal to 143.15 so it can not be C or D. And you dont need the extra x so it is choice A
The First one is the answer.
