Answer:

  • D) 6(4 1/2 m + 2/3)=629

Step-by-step explanation:

<em>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. </em>

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

  • 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

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

<u>A total mass is the sum of 6 packs and each pack is: </u>

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

<u>We can put it as equation:</u>

  • 6(4 1/2m + 2/3) = 629

Correct option is D

storchak [24]

Answer:

Each Person:

-In tips: $2

-Food Bill: $7.50

Step-by-step explanation:

Let's find the tip amount for each person. $16 for the whole group. Each person will give in $2 for the tips, for a total of $16 in tips.

Now that tips are done, we must subtract the amount of tips from the food bill, to see how much each person pays. $76 - $16 = $60.

Divide 60 by 8 to get.. 60/8= 7.5.

With 7.5 as an answer, we can conclude that each person paid $7.50 for the food bill.

I see you need to select solutions, may I see them to help you out? The description is pretty vague..
