The area of a rectangular horse pasture is 268,500 square yards. The length of the pasture is 5 yards less than three times the
Setler79 [48]

Answer:  width = 300

<u>Step-by-step explanation:</u>

Area (A) = Length (L) x width (w)

Given: A = 268,500

           L = 3w - 5

           w = w

268,500 = (3w - 5) x (w)

268,500 = 3w² - 5w

            0 = 3w² - 5w - 268,500

            0 = (3w + 895) (w - 300)

   0 = 3w + 895        0 = w - 300

  -985/3 = w             300 = w

Since width cannot be negative, disregard w = -985/3

So the only valid answer is: w = 300

PLZ HELP URGENT GET THE BRAINLIEST AND MORE POINTS
lord [1]

Answer:

  • The 27th term is 22

Step-by-step explanation:

Let the first term is a and common difference is d.

<u>The nth term is:</u>

  • aₙ = a + (n - 1)d

<u>We have:</u>

  • a₆ = 15
  • a₉ = 16

<u>The difference of these terms is:</u>

  • (a + 8d) - (a + 5d) = 16 - 15
  • 3d = 1
  • d = 1/3

<u>Then the first term is:</u>

  • a + 5*1/3 = 15
  • a = 15 - 5/3 = 13 1/3

<u>The nth term equation is:</u>

  • aₙ = 13 1/3 + 1/3(n - 1) = 1/3n + 13

<u>If the nth term is 22, find n:</u>

  • 1/3n + 13 = 22
  • 1/3n = 22 - 13
  • 1/3n = 9
  • n = 9*3
  • n = 27
