I need this one now I messed up on the other lol
ira [324]

The first one is X, then the second one would be X+1 ( adding one, makes it consecutive).


Now you have X + X+1 = 667

Simplify:

2x +1 = 667

Subtract 1 from each side:

2x = 666

Divide both sides by 2:

x = 666 /2

x = 333

The first marker is 333

The second marker = 333 +1 = 334

diamong [38]

Answer:

9 pieces

Step-by-step explanation:

28 inches rope cut into 3-inch pieces

  • 28/3 = 9 1/3

There is no matching answer choice, if given numbers are correct then the answer is 9 full pieces

---------

<u>Note:</u>

  • The close answer choice is 8
  • 28/8 = 3 1/2 or 3.5
  • So if cut into 3.5 inch pieces then it is 8 full pieces
  • just in case it was typo 3 instead of 3.5

Find The sum of the first 10 terms 8,20,32,44
nikklg [1K]

Answer:

S₁₀=620

Step-by-step explanation:

This is an arithmetic sequence with a common difference of d=12

The formula for an arithmetic series is Sₙ=(n/2)(a₁+aₙ) where aₙ is the nth term and a₁ is the first term.

We know that a₁=8 and d=12 where the 10th term would be a₁₀=8+(10-1)12=116.

Therefore, the sum of the first 10 terms of the arithmetic series is S₁₀=(10/2)(8+116)=(5)(124)=620
