Answer:

First side: 12 feet, second side: 16 feet

Step-by-step explanation:

We know that the second side is 4 feet longer than the first side. If the first side is x, then the second side is x+4

b) The total amount of the border is 28 feet, so we can say that first side+second side=28, or

x+(x+4)=28

2x+4=28

2x=24

x=12 feet is the first side

x+4 = 16 feet is the second side

We can check that 12 feet + 16 feet = 28 feet as stated by the problem

PSYCHO15rus [73]

Answer:

Step-by-step explanation:

44.75 - 28.50 = 16.25 so 16.25 divided by 3.25 equals 5 and 5 times 3.25 equals 16.25 and 16.25 plus 28.50 equals 44.75 so she bought 5 cards.
