Answer:
A) Yes, 7
Step-by-step explanation:
The given sequence An = {13, 20, 27, 34, ...}
Here the first term Ao = 13 and difference between the successive terms is (d) = 7
That is d = 20 - 13
d = 7
It is an arithmetic sequence. d = 7
Answer: Yes, it is arithmetic sequence and common difference (d) = 7
Thank you.
Answer: First option is correct.
Step-by-step explanation:
Since we have given that

Now, by factorising , we get

Now, we use the formula i.e.

By using this, we get ,

So,

Answer:
first one is 32
the second one is 53
Step-by-step explanation:
Question 1.). Solve:
2 (x - 1 / 2) = 3 (5 - 2x)
Simplify both sides of equation:
2( x - 1 / 2 ) = 3(5 - 2x )
(2) (x) + (2) ( -1 / 2 ) = (3) (5) + (3) ( -2x )
Distribute:
2x + - 1 = 15 + -6x
2x - 1 = -6x + 15
Add 6x to both sides:
2x - 1 + 6x = -6x + 15 + 6x
8x - 1 = 15
Add 1 to both sides:
8x - 1 + 1 = 15 + 1
8x = 16
Divide both sides by 8:
8x / 8 = 16 / 8
Answer: 2 (x - 1 / 2) = 3 (5 - 2x) ==========> x = 2
Question 2.).
M =======> Amount Malik need
Solution: =========> m ≥ 5
Inequality ========> 8 + 7 + 10 + m ≥ 30
25 + m ≥ 30
Interpretation ==========> Malik needs at least, $5 .00 to get to, $30.00 or more.
Is the solution reasonable ===========> YES
Hope that helps!!!!! : )
