coldgirl [10]

Answer:

8

Step-by-step explanation:

The numbers are 6 and 2x, then:

  • 1/6 + 1/(2x) = 7/24
  • 1/3 + 1/x = 7/12
  • (x+3)/(3x) = 7/12
  • 12(x+3) = 7*3x
  • 12x + 36 = 21x
  • 21x - 12x = 36
  • 9x = 36
  • x = 4

The other number is 2*4 = 8

Donna wants to decorate her bulletin board she has 38 meters of green ribbon to go around the bulletin board and she has to use
andreev551 [17]

If you are asking for the perimeter of the bulletin board the answer below will be correct!

Answer:

Square option: 9.5 Meters

Rectangle option: see explanation below

Step-by-step explanation:

To find the perimeter you must add the lengths of all the sides. Assuming the bulletin board is a SQUARE all four sides are going to be equal. Therefore you can divide 38 by 4 to get the length of one side (aka 9.5 meters).

Assuming the bulletin board is a RECTANGLE changes things up. You can pretty much pick any combination of numbers that will add up to 19 (because if it is a rectangle there are two pairs of equal side lengths). You could do 1 + 18, 5+14, 8+11. The options are really endless
