Answer:
x is 30
Step-by-step explanation:
1/2 ( x + 6 ) = 18
1/2x + 3 = 18
- 3 - 3
1/2x = 15
· 2 · 2
x = 30
The complete sequence solved by arithmetic progression is 5 8 11 14 17.
<h3>What is arithmetic progression?</h3>
The difference between every two successive terms in a sequence is the same; this is known as an arithmetic progression (AP). It is possible to obtain a formula for such nth term of a AP using this kind of development.
The numbers 5, 8, 11, 14,... belong to the arithmetic progression (AP) since they follow a pattern in which the previous number is added by 3 to get each new number.
nth term = a + (n-1)d
where, a is the initial term (=5)
n is the total terms in the series (=5)
d is the common difference (8-5=3)
Substitute the values in the formula to get the result;
5th term = 5 + (5-1)3
= 5 + (4×3)
5th term = 17
Therefore, the last term (5th term) of the series is 17.

Associative property of addition is used when you want to group addends.
This is mainly used to cluster set of numbers or in this case, addends. How do
you use the associative property when you break apart addends? Simple you group
them using the open and closed parentheses or brackets. Take for an example 1 +
1 + 2 = 4. Using the associative property you can have either (1 + 1) + 2 = 4
or 1 + (1 + 2) = 4 clustered into place.
Answer:
infinite solutions
Step-by-step explanation:
-3x = -x – 2x
Combine like terms
-3x = -3x
Add 3x to each side
-3x+3x = -3x+3x
0 =0
This is always true so there are infinite solutions
