Let k = the constant amount added to the sequence since this
is an arithmetic sequence
x = missing
number
You have to formulate an equation based on the sequence:
6 + k = x or k = x – 6
x + k = 30
Substitute the value of k to the second formula:
x + x – 6 = 30
2x = 36
x = 18
Therefore, the missing number is 18.
Step-by-step explanation:
4÷12= 0.333333333333
12÷4=3
Since 4÷12 answer is different from the others, it's A. Let me know if this is correct! :)
Answer:
I don't know if u want to know ask ur parents
Answer:
1. X= 56
2. X= -11/2 (When you solve you get this if you need it as a mixed number it's X= -5 1/2
Step-by-step explanation:
simplifying means: Reducing to lowest terms.
To solve for x simplify both sides of the equation, then isolate the variable.
