10. The width of a rectangle is doubled and the length is halved. This produces a square with perimeter of Pem. What is the perimeter (in cm) of the original rectangle? A) 2.5p B) 1.25P C) 0.5P D) 2P E) None of these

9514 1404 393

  B) 1.25P

Step-by-step explanation:

The perimeter of the square is P, so each side is 0.25P. That means the rectangle had sides of 2(0.25P) and 1/2(0.25P) = 0.5P and 0.125P.

The rectangle's perimeter is ...

  perimeter = 2(L+W) = 2(0.5P +0.125P) = 2(0.625P)

  perimeter = 1.25P . . . . matches choice B

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

i can't solve unless i know what the line is
