Jackie has fewer than 20 h to work on her jewelry. it takes her half an hour to make a necklace and an hour to make a bracelet. she wants to make x necklaces and y bracelets, and she wants at least twice as many bracelets as necklaces. select all inequalities that model this situation. x≥0 y≥2x x> 0 y> 2x 0.5x+y≤20 0.5x+y< 20

- The inequalities that model the given situation are 0.5x+y<20, y≥2x and x>0.

Explanation:-

Given:- The number of necklace she wants to make=x

The number of bracelet she wants to make=y

time taken to make necklace=

time taken to make bracelet =1 hour

As Jackie has fewer than/ less than 20 h to work on her jewelry.

⇒0.5x+y<20

And as she wants at least twice as many bracelets as necklaces.

⇒y≥2x and x>0. [since x =0 is not accepted value for this situation,the number of necklace cannot be zero]
