Answer:

  width:  7.5

  length: 22.5

Step-by-step explanation:

width:  x

length: 3x

Perimeter = 2L + 2W

60 = 2(3x) + 2x

60 = 6x + 2x

60 = 8x

x = 7.5

width:  x = 7.5

length: 3x = 3(7.5) = 22.5

Sunnyside Middle School wanted to add a new school sport, so they surveyed the students to determine which sport is most popular
ExtremeBDS [4]

Answer:

Lacrosse = 62 students

Swimming = 62 students

Soccer = 124 students

Football = 186 students

Step-by-step explanation:

Based on the information, we can draw some equations

<em>1.</em>    Lacrosse = Swimming

<em>2.</em>   Soccer = 2 * Lacrosse

<em>3.</em>   Football = 3 * Swimming

<em>4.</em>   Football + Soccer + Swimming + Lacrosse = 434

Lets solve for once sport at a time, I will start with Football.

I will put equation 1, 2 and 3 into equation 4

3Sw + 2L + L + L = 434

We can now again put equation 1 into the new equation 4

3L + 2L + L + L = 434

Simplify

7L = 434

L = 434 ÷ 7

L = 62 students

Since L = Sw, 62 students did swimming also

We can put L into equation 2 to solve for So

So = 2 * 62

So = 124 students

And now we can put Sw into equation 3 to solve for F

F = 3 * 62

F = 186 students

a = $2600(1+(0.0675/1))¹*¹⁴

a = $6488.19
