Answer:
Step-by-step explanation:
Distribute the parenthesis
Add 20 to both sides
Divide both sides by 2
Hope this helps
Answer:
a7 = 36
Step-by-step explanation:
Here, we are to use the recursive formula to calculate the 7th term( we add the preceding term to 4 so as to get the succeeding term)
a1 = 12
using the recursive formula given in the question
a2 = 12 + 4 = 16
a3 = 16 + 4 = 20
a4 = 20 + 4 = 24
a5 = 24 + 4 = 28
a6 = 28 + 4 = 32
a7 = 32 + 4 = 36
Answer:
Step-by-step explanation
6n - 6 = 2 (n+1)
Simplify 2 (n+1)
6n - 6= 2n +2
Move all terms related to n to the left side of the equation
4n -6 =2
Move all terms not related to n to the right side of the equation
4n =8
Divide each term by 4 then simplify
n=2
Answer:
x = 0
Step-by-step explanation:
(x)=5x+19(x)=-2x+15
We move all terms to the left:
(x)-(5x+19(x))=0
We add all the numbers together, and all the variables
x-(+24x)=0
We get rid of parentheses
x-24x=0
We add all the numbers together, and all the variables
-23x=0
x=0/-23
x=0
