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
Answer:
9 pieces
Step-by-step explanation:
28 inches rope cut into 3-inch pieces
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
Answer:
A=.666666(repeated) because 28/42=.666666 and 14/21=.66666
B= 6 by 3 because 42x1/7=6 and 21x1/7=3
Step-by-step explanation:
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
