5x-y10 We're basically just multiplying the 5 by x and the y by 5 and -2.
(5/x= 5x) + (y/-2/-5)
Answer:
Ana made a mistake from line 2 to 3
Step-by-step explanation:
From line 2 to 3, on the left side, ana <u>added</u> 2 and 3 but completely ignored the - in front of the 3. the correct answer would have been<u> -x - 21 = 3x + 19</u>
Based on the calculations, all of the numbers belong to this arithmetic sequence.
<h3>How to calculate an arithmetic sequence?</h3>
Mathematically, the nth term of an arithmetic sequence can be calculated by using this expression:
<u>Where:</u>
- d is the common difference.
- a₁ is the first term of an arithmetic sequence.
- n is the total number of terms.
Next, we would determine the common difference as follows:
d = a₂ - a₁
d = 105 - 99 = 6.
d = a₃ - a₂
d = 111 - 105 = 6.
d = a₄ - a₃
d = 117 - 111 = 6.
Based on the calculations, all of the numbers belong to this arithmetic sequence.
