Answer:

9

Step-by-step explanation:

x = first number

3x = second number

2x = third number

27 = x + 3x+ 2x

27 = 6x

x=4.5 (first number)

3(4.5) = 13.5 (second number)

2(4.5) = 9 (third number)

(4.5 + 13.5 + 9) /3 = 9

Wow after doing all that I realized that all you had to do was 27/3 since there's 3 numbers.

“Camilla makes and sells jewelry. She has 8,160 silver beads and 2,880 black beads to make necklaces. Each necklace will contain
Usimov [2.4K]
<h3>Answer:</h3>

96 necklaces

<h3>Step-by-step explanation:</h3>

To find out how many necklaces Camilla can make, we need to see how many times the required number of beads "goes into" the available number of beads.

Silver: 8160/85 = 96

Black: 2880/30 = 96

Camilla has enough beads to make 96 necklaces.

_____

<em>Comment on this answer</em>

Obviously, if one of the quotients is smaller than the other, Camilla can only make as many necklaces as are supported by the constraining resource.

Even if she had 3000 black beads (way more than 2880), she could still only make 96 necklaces (for example) because she would run out of silver beads making that 96th necklace. (There would be 120 black beads left over in that scenario.)

gtnhenbr [62]

Answer:

  • 2820 seats
  • aₙ = 3n + 9

Step-by-step explanation:

<u>This is an AP with:</u>

  • The first term a₁ = 12
  • Common difference d = 3
  • Number of terms n = 40

<u>Number of the seats:</u>

  • Sₙ = 1/2*n(a₁ + aₙ) = 1/2n(2a₁ + (n - 1)d)
  • S₄₀ = 1/2*40(12*2 + 39*3) = 2820 seats

<u>Formula of nth term:</u>

  • aₙ = a₁ + (n - 1)d
  • aₙ = 12 + (n - 1)*3 = 12 + 3n - 3 = 3n + 9
  • aₙ = 3n + 9
