Answer:

  • D) 6(4 1/2 m + 2/3)=629

Step-by-step explanation:

A display has 6 packs of marbles with a total mass of 629g. The packaging of each pack has a mass of 2/3 g and each marble has a mass of 4 1/2 g.

Which equation can we use to determine m, the number of marbles per pack?

  • A 6*4 1/2 m+ 2/3=629
  • B 6 m(4 1/2+ 2/3)=629
  • C 6 m+4 1/2+ 2/3=629
  • D 6(4 1/2 m + 2/3)=629

================================

A total mass is the sum of 6 packs and each pack is:

  • m marbles + packaging = 4 1/2 m + 2/3

We can put it as equation:

  • 6(4 1/2m + 2/3) = 629

Correct option is D
