\LARGE{ \underline{\underline{ \sf{Required \: answer:}}}}

Let gift box be x and the Christmas tree be y.

<u>Then:</u>

The equation formed by plugging x in place of gift box and christmas tree will be:

(1) 2x + y + 3 = 16

➛ 2x + y = 13

(2) 3x + y + 1 = 14

➛ 3x + y = 13

Subtracting (2) from (1), And we get:

➛ 3x + y - 2x - y = 0

➛ x = 0

Then, y = 13

<u>We </u><u>need </u><u>to </u><u>find:</u>

• yx + x

= 13 × 0 + 0

= 0

<u>Hence</u><u>:</u><u>-</u>

  • The cost of all the items will be 0. Congrats for Christmas Bingo!!!

Suppose that you need to build as many chairs as possible. Each chair requires one seat, one back, and four legs. If you have 12
GrogVix [38]

Answer:

  legs limit the number of chairs that can be built

Step-by-step explanation:

The maximum number of chairs that can be built will be the minimum of the number of parts divided by the number of parts needed for each chair, as computed across the different kinds of parts required.

  seats: 12 available, used 1 per chair: 12/1 = 12 chairs possible

  backs: 15 available, used 1 per chair: 15/1 = 15 chairs possible

  legs: 44 available, used 4 per chair: 44/4 = 11 chairs possible

The maximum number of chairs that can be built will be the minimum of 12, 15, and 11. That is, 11 chairs can be built, limited by the number of available legs.
