I have a triangular garden such that the largest side is 6 ft less than twice the smallest and medium side is 5 ft larger than t
earnstyle [38]
Given:
Triangular garden
smallest side: x
medium side: x + 5ft
largest side: 2x - 6ft
Perimeter: 47 ft.

Perimeter = smallest side + medium side + largest side
47 ft = x + x + 5ft + 2x - 6ft
47 ft - 5ft + 6ft = 4x
48ft = 4x
48ft / 4 = 4x / 4
12 ft = x

smallest side: x = 12 feet
medium side: x + 5ft = 12ft + 5ft = 17 ft
largest side: 2x - 6ft = 2(12ft) - 6ft = 24ft - 6ft  = 18ft

Perimeter: smallest + medium + largest
47ft = 12ft + 17ft + 18ft
47ft = 47ft

The football team needs to raise at least $7,000 for new football uniforms. An anonymous donor gave the team $1,250 toward their
jok3333 [9.3K]

Answer: There are 58 players to raise $100 to meet their goal.

Step-by-step explanation:

Since we have given that

Amount to raise = $7000

Amount given the team by the donor = $1250

Amount each player is able to raise = $100

Let the number of player be 'x'.

According to question, we get that

1250+100x\geq 7000

So, the required number of players would be :

100x\geq 7000-1250\\\\100x\geq 5750\\\\x\geq \dfrac{5750}{100}\\\\x\geq 57.5

Hence, there are 58 players to raise $100 to meet their goal.
